The X values of the equation will be 2, -1 0 and 4 because if you plug the numbers in you will get y. ( using y=mx+b)

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. $(2,-3)$-->$2$ $(-1,0)$-->$-1$ $(0,4)$-->$0$ $(-1,5)$-->$-1$ $(4,-2)$-->$4$ That gives you the numbers $2, -1, 0,$ and $4$.
