Question

Which system of equations is represented by the graph?

A. Y=x^2+4x
Y=-x^2+x+12
B. Y=x^2-8
Y=-x^2+16
C. Y=x^2
Y=-x^2-x-16
D. Y=x^2+8
Y=-x^2+16

Answer 1

D

Explanation:

Since we know that both parabolas are on the y-axis, it can't be A or C.

We also know they are above (0,0), so it can't be option B.

That leaves option D.
