Slope:
Y-intercept:
Equation:
is this graph proportional? _____

Answers

Answer:

Slope: 1

Y-Intercept: (0,4)

Equation: y=1x+4

Step-by-step explanation:

To solve for slope you need to pick 2 points on the graph (ex. 2,6 and 4,8 ), then you use the formula to find the slope.

For Y-Intercept you just look for where the line intercepts on the y-axis (ex. 0,4).

If the line doesn't touch the origin (0,0), then it isn't proportional.

For the equation it's y=mx+b or, if its proportional then y=mx. The Y-Intercept will always be b. The slope represents m. The x is the variable.

Step-by-step explanation:

Answer:

C. m = -2/3

Step-by-step explanation:

Slope is rise/run (rise-over-run).

It falls 2, so the "rise" is -2. It moves right by 3, so the "run" is 3.

Therefore, -2/3.

Find the Inverse of the Function

y= 10x^2 - 4

Answers

Hello.

1. Switch y and x.
x = 10y^2 - 4
2. Isolate y.
x + 4 = 10y^2
(x + 4)/(10) = y^2
y = sqrt[(x + 4)/(10)]
3. Replace y with f^-1(x)
f^-1(x) = sqrt[(x + 4)/(10)]

Good luck to you!

The inverse of the function y = 10x² - 4 is given by y = ±√[(x + 4) / 10].

To find the inverse of the function y = 10x² - 4, we need to interchange the variables x and y and then solve for y.

Let's start by rewriting the equation with x and y switched:

x = 10y² - 4

Next, let's isolate the term with y by adding 4 to both sides:

x + 4 = 10y²

To isolate y, divide both sides by 10 and then take the square root:

(y²) = (x + 4) / 10

y = ±√[(x + 4) / 10]

Therefore, the inverse of the function y = 10x² - 4 is given by y = ±√[(x + 4) / 10].
