Question

Find the inverse:
f(x) = x^2

Answer 1

So i need the inverse function of f(x)=x^2 . I need help understanding it

Answer 2

do you know what inverse means??

Answer 3

Yeah, its the opposite

Answer 4

so do you know how the graph f(x) = x^2 looks like?

Answer 5

Not really

Answer 6

it looks like that

Answer 7

Oh ok, so how will that help me finding the inverse function? Like what are the steps to finding it?

Answer 8

you just need to use the function \[\sqrt{y}\]

Answer 9

How will that help ?

Answer 10

well that is the inverse equation so when you plug in the number the you squared into the squre root it will give you the inverse

Answer 11

EX:
Square:(-2)2 = 4
Inverse (Square Root): √(4) = 2
