Answer 2

(2,3) means x=2, y=3.
To see if (2,3) is on the graph of h(x) = -2x²
substitute x=2, and see if the result y=h(2)=-2(2)² equals 3. Since the result y=h(2)=-2(2)²=8 does not equal 3, we conclude that (2,3) is not on the graph of h(x).

Do this similarly for all options to find the point on the graph.
