Question

Let f(x) = x2 - 16. Find f-1(x).

Answer 1

Do u know how to take inverse

Answer 2

Not really.

Answer 3

\(f(x)=y\\y=x^2-16\\x=y^2-16\)
now, solve for y.

Answer 4

16x=y^2/16x

Answer 5

nope.
transpose 16 to the left side by adding 16 on both sides.
Then you have to get the square root of both sides.
