Best ResponseYou've already chosen the best response.1Inverse function? Simply replace "x" with "y" and vice versa, like this:\[f(x)=x^2  16 \quad or \quad y=x^2  16 \rightarrow reversing \rightarrow x=y^216\]

Best ResponseYou've already chosen the best response.1Yet\[y^2=x+16 \rightarrow \quad Two \quad functions \rightarrow y=\sqrt{x+16} \quad or \quad y=  \sqrt{x+16}\]

Best ResponseYou've already chosen the best response.1Or simply\[y= \pm \sqrt{x+16}\], answer "c", ok?
