If f(x) = x2 -1, what is the equation for f–1(x)?

Step-by-step explanation:

f(x) = x^2 -1

We need to find f^-1(x)

WE find inverse of f(x)

Replace f(x) with y

Replace x  with y  and y with x

Solve for y

add 1 on both sides ,

To remove square , take square root on both sides

Replace y with f^-1

Inverse function is

Step-by-step explanation:

Given that

Now using that equation of f(x), we need to find equation of the inverse function

Step 1: Replace with y

Step 2: Switchx and  y

Step 3: Solve for y

take square root of both sides

Hence inverse function is
