Suppose that the function fis defined, for all real numbers, as follows.
f(x) =
x-4 if x < 2
-2x+2 if x ≥2
Graph the function f. Then determine whether or not the function is continuous.
See attachment for the graph and the function is a continuous function.
How to graph the function?The function definition is given as:
f(x) = [ x-4 if x < 2
[-2x+2 if x ≥2
The above function is a piecewise function.
So, we plot each function by its domain
Having said that, the next step is to plot the graph of the functions in f(x) according to their domain
See attachment for the graph
Also, the function is a continuous function.
This is so because there is no break in the function value i.e. domain and range are the set of all real values

Which fruit snack cost less per pound? How much less?
Each pound of brand B costs 0.33 dollars less than each pound of brand A.
Which fruit snack costs less per pound?
Here we need to find the cost per pound for both brands, to get that, we need to get the quotient between the costs and the number of pounds.
For brand A the cost is $37.80 and you get 35 pounds, then the cost per pound is:
A = $37.80/35 = $1.08
Then each pound for brand A costs 1.08 dollars.
Now let's do the same for brand B, the cost is $33.75, and you get 45 pounds, then the cost per pound is:
B = $33.75/45 = $0.75
Then each pound for brand B costs 0.75 dollars.
So brand B is cheaper, and the difference is:
1.08 dollars - 0.75 dollars = 0.33 dollars.
Each pound of brand B costs 0.33 dollars less than each pound of brand A.

3/9 = x/12
Simplify your answer as much as possible.
Answer:
Step-by-step explanation: We can begin by rewriting the equation. That would look like so:
3/9 = x/12
We need to solve for x. Our first step is to identify a common denominator. Let's list the multiples of each denominator.
9: 9, 18, 27, 36
12: 12, 24, 36
Our common denominator is 36.
Now, let's cross multiply:
3 x 12 = 36
9 x ? = 36
36 ÷ 9 = 4
x = 4
Final answer: 3/9 = 4/12, where x = 4.

3x + 6 - 6 = 248
Answer:

Step-by-step explanation:
3x+6-6=248
3x=248
x=82.7
Answer:
[tex]82.6[/tex]Step-by-step explanation:
Simplify both sides of the equation:3x + 6 − 6 = 248
3x + 6 + − 6 = 248
( 3x ) + ( 6 + − 6 ) = 248 (ℂ )
3x = 248
Divide both sides by 3:3x / 3 = 248 / 3
x = 248 / 3
x = 82.6
2(3x-2)-4x+1= 9 solve for x
Answer:x=6
Step-by-step explanation:
6x-4-4x+1=9
subtract 1 from both sides
6x-4-4x=8
add 4 to both sides
6x-4x=12
subtract 6x by 4x
2x=12
divide by 2 on both sides
x=6

Answer: 12
Step-by-step explanation: we know that a^2 + b^2 = c^2, pythagorean theorem. We're given a and c in this case, which are 16 and 20 respectively. so that means 16^2 + x^2 = 20^2. After evaluating the equation, we get 256+ x^2 =400. now subtract 256 from both sides and then we get x^2 = 144. take the square root of both sides and we end up with x = 12.
The festival that the total attendance for 2014 will be twice the attendance in 2012. What is the projected attendance for 2014?
The projected attendance for 2014 in the form of linear equation is written as y = 2x.
What is linear equation in two variables?A linear equation in two variables is one that is written in the form ax + by + c = 0, where a, b, and c are real numbers as well as the coefficients of x and y, i.e. a and b, are not equal to zero.
For instance, 10x+4y = 3 and -x+5y = 2 are two-variable linear equations.The solution to such an equation is just a pair of values, one is for x and one for y, which also equalizes the 2 sides of an equation.Now, for the given question;
Let us consider that the total attendance in 2012 be 'x'.
And the total attendance in 2014 be 'y'.
Then, the total attendance for 2014 will be twice the attendance in 2012.
Thus,
y = 2x.

What is the image of a quadrilateral after applying a dilation factor?
A dilation is a kind of rigid transformation, that is, a transformation applied on geometric loci such that its Euclidean distance is conserved. According to the statement, we must the following dilation to generate the image:
P'(x, y) = (3 / 2) · P(x, y)
If we know that Q(x, y) = (- 1, 4), T(x, y) = (0, - 2), S(x, y) = (2, - 2) and R(x, y) = (1, 2), then the vertices of the images are:
Q'(x, y) = (3 / 2) · (- 1, 4)
Q'(x, y) = (- 1.5, 6)
T'(x, y) = (3 / 2) · (0, - 2)
T'(x, y) = (0, - 3)
R'(x, y) = (3 / 2) · (1, 2)
R'(x, y) = (1.5, 3)

7. One hundred three and one half gallons drained in the last 9 minutes from a pool. The water drains at a constant rate. How many gallons drain per minute from the pool?
The Number of Gallons drained per minute from the pool is; 931.5 gallons drained per minute
What is the constant rate?Constant rate is simply a rate that remains unchanged regardless of change in parameters.
Now, we are told that One hundred three and one half gallons drained in the last 9 minutes from a pool. Thus;
Amount of gallons that drained from pool = 103¹/₂ gallons = 207/2 gallons
Time it took to drain = 9 minutes

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.
In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain.
The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

Suppose your function is increasing from the interval [2,5] what can you conclude if the function is even? what can you conclude if it is odd?
Using the concept of even and odd functions, it is found that, considering the function has a local max at (-1,3):
If the function is even, it will have another local max at (1,3).If the function is odd, it will have a local min at (1,-3).For a function increasing on [2,5], we have that:
If the function is even, it will be decreasing on [-5,-2].If the function is odd, it will be increasing on [-5,-2].What are even and odd functions?In even functions, we have that f(x) = f(-x) for all values of x.In odd functions, we have that f(-x) = -f(x) for all values of x.If none of the above statements are true, the function is neither.Hence, considering the function has a local max at (-1,3):
If the function is even, it will have another local max at (1,3).If the function is odd, it will have a local min at (1,-3).For a function increasing on [2,5], we have that:
If the function is even, it will be decreasing on [-5,-2].If the function is odd, it will be increasing on [-5,-2].For even functions it will decrease because we have that f(4) > f(3), for example, hence f(-4) > f(-3).
For the odd function it will increase because if f(4) > f(3), then f(-3) > f(-4) due to the negative signal.
