Question

What is the inverse of the function y= x^2-12

Answer 1

Answer:

$y=\sqrt{x+12}$

Step-by-step explanation:

To find the inverse of a function, what I like to do is to switch the places of x and y, and then try to isolate y again like so:

$x=y^2-12$

$x+12=y^2$

$y=\sqrt{x+12}$

Hope this helps!
