Find the inverse of the function y=2x^2+2

Tatiana [17]

The inverse of the function is y = $\sqrt{\frac{x - 2}{2}}$

In order to find this, you must start by switching the y and x values. Once you do this, you can solve for the new y value and that will be in inverse. The work is done for you below.

y = 2x^2 + 2 ---> switch x and y

x = 2y^2 + 2 ---> subtract 2 from both sides

x - 2 = 2y^2 ---> divide both sides by 2

$\frac{x-2}{2}$ = y^2 ---> take the square root of both sides.

$\sqrt{\frac{x - 2}{2}}$ = y

Find the range of the following equation for the domain {-4, 0, 3} f (x) = -2x^2 -3

Tamiku [17]

The range of the function is {-34, -2, -20}

<h3>How to determine the range?</h3>

The function is given as:

f(x) = -2x^2 - 2

The domain is {-4, 0, 3}

Substitute the domain values in the function.

f(-4) = -2(-4)^2 - 2 = -34

f(0) = -2(0)^2 - 2 = -2

f(3) = -2(3)^2 - 2 = -20

This means that the range of the function is {-34, -2, -20}
