Question

$f(x)=\sqrt x+2$
What is the inverse?

Answer 1

Answer:

$(x-2)^2$

Step-by-step explanation:

To find the inverse of this function, you need to replace the location of the x and the y.

You start with $y=\sqrt{x}+2$. Now, replace the x and the y, and try to isolate the y.

$x=\sqrt{y}+2\\x-2=\sqrt{y}\\y=(x-2)^2$

Hope this helps!
