Question

What is the inverse of y equals x squared + 2

Answer 1

To get the inverse relation of any expression, simply start off by doing a switcharoo on the variables, and then solve or "y".

$\bf \boxed{y}=\boxed{x^2}+2\qquad inverse\implies \boxed{x}=\boxed{y^2}+2 \\\\\\ x-2=y^2\implies \sqrt{x-2}=y\impliedby f^{-1}(x)$
