Question

Which of the following ordered pairs lies on the graph of h(x) = -2x^2?

(1, -4)
(1, -2)
(1, 4)

Answer 1

given, y= -2x^2;
so, when x=1, y= -2((1)^2)= -2
so pair which lie on graph is (x,y) is (1,-2)

Answer 2

From the function h(x) = -2x^2 or y = -2x^2,
when x = 1, y = -2(1)^2 = -2.

Hence, the answer is (1, -2).
