Question

What is the equation !!! Math 3. 10 points HELP NEEDED!!!

Answer 1

B.

`{f}^( - 1) (x) = {x}^(2) - 3`

Step-by-step explanation

Given

`f(x) = √(x + 3)`

Let

`y= √(x + 3)`

Interchange x and y.

`x= √(y + 3)`

Square both sides

`{x}^(2) = y + 3`

Solve for y

`y = {x}^(2) - 3`

Therefore the inverse of f(x) is

`{f}^( - 1) (x) = {x}^(2) - 3`
