When writing the range for the quadratic
parent function we use a bracket next to
infinity. Why do we use parenthesis next to
zero for the range of the exponential parent
function?
the value y = 0 does not belong to the range, that is why we need to use parenthesis next to the range.
Why do we use parenthesis next to zero for the range of the exponential parent function?When we write in interval notation, the parenthesis are used to denote that the "ends" of the interval don't belong to the interval.
This means that in (a, b).
a and b don't belong to that interval.
While if instead we wrote [a, b]
In that case, a and b belong.
For the case of the exponential function:
y = a^x
As x tends to really large negative values, the value of y will tend to zero asymptotically. This means that y is really close to zero, but it is never equal to zero.
Then the value y = 0 does not belong to the range, that is why we need to use parenthesis next to the range.

Sophia buys 13 bottles of cranberry juice at the corner store for a total cost of $7.02. If each bottle costs the same amount, how much is 14 bottles of juice?
The cost for 14 cranberry juice bottles would be $7.56
In this question, Sophia buys 13 bottles of cranberry juice at the corner store for a total cost of $7.02
If each bottle costs the same amount, we need to find the amount for 14 bottles of juice.
Let x be the cost of one bottle of cranberry juice.
13 bottles of cranberry juice costs $7.02
So, we get an equation,
13x = $7.02
We solve above equation to find the cost of 1 bottle of cranberry juice.
x = $0.54
By unitary method the cost for 14 cranberry juice bottles would be,
14 × 0.54 = $7.56

11. There are 8 fluid ounces in one cup. If you
double the amount of fluid ounces, will the
amount of cups also double? Write an
argument that can be used to defend your
solution.
Answer:
Yes
Step-by-step explanation:
Imagine you have 1 cup. It’s 8 oz. Then imagine someone came up and doubled the # of ounces you have. Now you have 16 oz or 2 cups. 2 cups is double one.
This isn’t a good explanation, sorry lol
But honestly, just think of it as a fraction, what you do to the top, you do to the bottom. As long as you do the same thing to the cups that you did to the ounces, the cups and ounces will remain proportional.

The diameter of a strand of rope is 1.2 × inch. The diameter of a strand of floss is 2.0 × inch.
How much longer is the diameter of the strand of rope than the diameter of the strand of floss?
A. 2.0 × inch
B. 1.0 × inch
C. 2.0 × inch
D. 1.0 × inch
The rope's diameter is 10⁻³ inches greater than that of the floss, for example.
The diameter of a stand of rope is 1.2 × 10⁻³ inch.
The diameter of a strand of floss is 2 × 10⁻⁴ inches.
Subtract the diameter of the floss strand from the diameter of the rope to determine how much longer the diameter of the rope is than the diameter of the floss.
Therefore, the length by which the diameter of the strand of rope is longer than the diameter of the strand of floss will be:
= 1.2 × 10⁻³ inch - 2 × 10⁻⁴ inches
Now,
= 12 × 10⁻⁴ inch - 2 × 10⁻⁴ inch
= 10 × 10⁻⁴ inch

In triangle PQR,work out the values of a ,b and c.Give your reason for you answer .
Answer:
m∠a = 100°
m∠b = 100°
m∠c = 110°
Step-by-step explanation:
Calculation of m∠a
∠a is an exterior angle of ΔPST .
Therefore m∠a = sum of the interior angles of ΔPST
m∠a = 30 + 70 = 100°
Calculation of m∠c
∠c and ∠PST are supplementary so their measures must add up to 180°
m∠c + 70° = 180° so m∠c = 180 - 70 = 110°
Calculation of m∠b
QRST is a quadrilateral.
The sum of the interior angles of the quadrilateral = 360°
So m∠a + m∠b + 50 + m∠c = 360°
We have already computed ∠a = 100° and ∠c = 110°
So 100 + m∠b + 50 + 110 = 360°
260 + m∠b = 360
m∠b = 360 - 260 = 100°

How would I solve these problems
Answer:
1a. -( x + 1)² + 4
1b. y-intercept at y = 3
1c. x-intercepts at x = -3 and x = 1
Derivation of 1b and 1c below
Step-by-step explanation:
Question 1a
The vertex equation form of a parabola is given by
y = a(x-h)² + k where (h, k) are the coordinates of the vertex
If a > 0 then the parabola is facing up(vertex is at a minimum) and if a < 0 then parabola is facing down (vertex at a maximum)
From the graph we see that the parabola is facing down so a = -1
The vertex is at (-1, 4) so h = -1 and k = 4
Therefore the equation of the parabola is
y = -1(x - h)² + k = -1(x- (-1))² + 4 = -1(x + 1)² + 4
y = -( x + 1)² + 4 (Answer 1a)
Question 1b
The y-intercept is the y-value where the parabola crosses the y-axis. From the graph we see that the parabola crosses the y-axis at y = 3 and x = 0
So y-intercept from the graph is 3
To solve algebraically, set x = 0 in the parabola equation and solve for y
We get, for x = 0,
y = - (0 + 1)² + 4
y = -(1²) + 4 = -1 + 4 = 3
Hence verified
Question 1c
There will be two x-intercepts for a parabola. Looking at the graph we see that the parabola intersects the x-axis at two points (-3, 0) and (1, 0). So the two x-intercepts are -3 and 1
Algebraically we can determine the x-intercepts by setting y = 0 and solving for the two values of x
Setting y = 0 in the parabolic equation, we get
y = 0 = -(x + 1)² + 4
Switch sides
-(x + 1)² + 4 = 0
-(x + 1)² = -(x² + 2x + 1) = -x² -2x - 1
-(x + 1)² + 4 = 0
==> -x² -2x - 1 + 4 = 0
==> -x² - 2x +3 = 0
Multiply by -1 both sides
==> x² + 2x - 3 = 0
Solve this quadratic equation by factoring
x² + 2x - 3 = (x - 1)(x + 3) = 0
The solutions are
x - 1 = 0 ==> x = 1
x + 3 = 0 ==> x = -3
Hence verified

How to understand algebra 1 dot plots
We can understand dot plot by taking example of be the choice of foods that you and your friends ate for snacks.
A dot plot is a type of graphical display that uses filled circles (dots) and a simple scale to compare counts (frequencies) within a category or group when working with small data sets with few groups . A chart with letters or words (non-numeric categories) on the x-axis is called a qualitative dot plot. The dot plot above is a qualitative dot plot because A, E, I, O, and U are not numeric. Qualitative variables cannot be described in terms of center, spread, or shape. If the x-axis contains numbers (numerical categories), it is called a quantitative dot plot. This dot plot can be described in terms of center, spread, or shape.Dot plots are used to represent small amounts of data. To analyze this chart, let's say four people are having a snack together. Snack selections are pizza, burgers, fries, and pasta. Using the dot plant, we can see that everyone chose pizza. Also, her 3 other people in your group added burgers to their snack plates. The graph also shows that two people in the group added French fries and one person in the group added pasta to their meal.

Arthur is 7 years older than his brother. In 8 years, Arthur will be twice his brother's current age. How old is Arthur now?
Answer:
15 years old
Step-by-step explanation:
Answer: 22
Step-by-step explanation:
this problem is solved by a system of equations
Let Arthur’s current age be represented by:a
His brother’s current age will be represented by: b
The first equation will be:
a = 7 + b
The second equation will be:
a + 8 = 2b
now we solve for the equations. Plug in a = 7+b into a in the second equation.
So now we have
b+7+8=2b
Simplify:
B+15=2b
15=b
We aren’t done yet though
Arthur’s brother is 15 years old but since he is 7 years older we need to add 7 to 15
Hence, Arthur is 22 years old.
