Answer
$y=\sqrt{2x}$
$-12\leq x \leq12$
$-8\leq y \leq8$
Work Step by Step
Type the function $y=\sqrt{2x}$ into your graphing calculator and set the window to the bounds that were given. In this case we have $-12\leq x \leq12$ and $-8\leq y \leq8$
Your graph should look similar to the one posted here.
