Answer:
The answer to your question is [tex]f(x) = \sqrt{x+ 4}[/tex]
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
[tex]y = \sqrt{x+ 4}[/tex]
4.- Change "y" for f(x)
[tex]f(x) = \sqrt{x+ 4}[/tex]
