Question

Find the inverse function of
(Show work)

f(x)=x^2-4

Answer 1

The answer to your question is
`f(x) = √(x+ 4)`

Explanation:

f(x) = x² - 4

Process

1.- Change f(x) for y

y = x² - 4

2.- Change "x" for "y" and "y" for "x".

x = y² - 4

3.- Make "y" the object of the equation

y² = x + 4

`y = √(x+ 4)`

4.- Change "y" for f(x)

`f(x) = √(x+ 4)`
