Answer:

The answer to your question is f(x) = \sqrt{x+ 4}

Step-by-step 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 = \sqrt{x+ 4}

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

                                          f(x) = \sqrt{x+ 4}
