Question

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

Answer 1

its the last one.

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

`(x)/(2)` -
`(2)/(2)` =
`y^(2)`

reduce fraction and square root both sides
