Question

which function at the bottom is the inverse of f(x) = x2 − 36?

x squared over 36

±6square root of x

1 over quantity x squared minus 36

±square root of the quantity x plus 36
need help

Answer 1

To solve for an inverse switch y and x and then solve for y

Answer 2

I've tried that and keep coming up with the wrong answer

Answer 3

Well show us your work and process, we will try to see where you messed up

Answer 4

1.)let f(x)=y
2.) switch x and y
3.)solve for y( rearrange the equation in terms of y)

Answer 5

f(x)=x2-36
y=x2-36
x=y2-36 ??

Answer 6

ok whats next--isolate the y

Answer 7

how?

Answer 8

add 36 to both sides

Answer 9

what did you get??

Answer 10

x+36=y2?

Answer 11

ok how would get y by itself

Answer 12

that's what i'm trying to remember lol

Answer 13

sqrt both sides

Answer 14

ok thanks

Answer 15

good job!!!!!

Answer 16

An Inverse Function or just any Inverse Relation? I do wish these questions would be more specific.
