Determine the restrictions on the constants A, C and E such that the following equation is a parabola with a vertical axis of symmetry.(adsbygoogle = window.adsbygoogle || []).push({});

Ax^2+Cy^2+x+Ey=0

a) A=0, C cannot=0, E cannot=0

b) A=0, C cannot=0, E=0

c) A cannot=0, C=0, E=0

d) A cannot=0, C=0, E cannot=0

i know that A cannot=0 and C=0....how about the x and y...what do they have to do with axis of symmetry?
