Question

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

Answer 1

Answer:

its the last one.

Step-by-step explanation:

easy way to do inverse functions:

write out equation :

y = 2$x^{2}$ + 2

Switch the x and y:

x = 2$y^{2}$ + 2

Solve for y :

x = 2$y^{2}$ + 2

subtract 2 both sides

x - 2 = 2$y^{2}$

Divide both sides by 2

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

reduce fraction and square root both sides
