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

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

Answer:
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
