Tell whether the parabolic graph of the equation opens up, down, to the left, or to the right. $$y ^ { 2 } = - 4 x$$
A) opens to the right
B) opens down
C) opens to the left
D) opens up

Question

Quizplus · Accepted Answer

The equation $y^2 = -4x$ is a form of a parabola that opens horizontally. Since the coefficient of $x$ is negative, the parabola opens to the left.
