Question

Which equation is the inverse of y = x2 + 16?

Answer 1

as you already know to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

`\bf y=x^2+16\implies \stackrel{\textit{quick switcheroo}}{\underline{x}=\underline{y}^2+16}\implies x-16=y^2\implies √(x-16)=\stackrel{f^(-1)(x)}{y}`
