Question

Select the points that lie on the function h(x) = 3x 2.

(1, 3)
(1, 9)
(-1, -3)
(-1, 3)

Answer 1

is h(x)= \[3x^2\]?

Answer 2

idk?

Answer 3

assuming it's \[3x^{2}\] because otherwise saying 2*3*x makes no sense,
just plug in the x and y values in the options and see if they're true
in this case the answer is the first one and the last one : (1, 3) and (-1, 3)
