Answer

$I$. $\{-1,0,2,4\}$

Work Step by Step

The domain of a function includes all of the $x$-values. In each ordered pair, there is $(x,y)$ therefore, take out the $x$ value. $(2,-3)$-->$2$ $(-1,0)$-->$-1$ $(0,4)$-->$0$ $(-1,5)$-->$-1$ $(4,-2)$-->$4$ That gives you the numbers $2, -1, 0,$ and $4$, so the domain is: $\{-1,0,2,4\}$ The correct answer is $I$.
