Question

which equation represents the parabola shown on the graph? y^2=-2x y^2=-8 y^2=-2y y^2=-8y

Answer 1

Answer:

Choice B is correct

Step-by-step explanation:

The graph of the parabola opens towards the left. This implies that the general form of the equation of the parabola will be;

$y^{2}=f(x)$

Nevertheless, the points (-2, -4) and (-2, 4) lie on the graph of the parabola. We substitute x = -2 in the equations having the form above.

In the second equation, we have;

$y^{2}=-8(-2)\\\\y^{2}=16\\\\y=\sqrt{16}=+4, -4$

This is thus the equation of the parabola graphed.
