Question

Which of the equations below could be the equation of this parabola?

A. y = 4x2
B. x = 4y2
C. X=-4x2
D. Y=-4x2

Answer 1

D

Explanation:

The graph opens downward so we would expect the integer to be negative. Also because the parabola opens downward you cannot have the equation be X=, this leaves Y=-4xsquared as the only viable option

Answer 2

The answer is D final bc it’s is on y axis and the -4 comes because it’s going down the the y axis. D is final answer
