Question

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

Answer 1

Y = -4x^2

The answer is D

Answer 2

Answer: D. $y=-4x^2$

Step-by-step explanation:

From the given picture we can see that, there is an parabola opening downwards where its vertex lies at origin.

Also y axis is the axis of the symmetry for the given parabola.

Since, the standard equation of a parabola with vertex at origin , and open downwards is $y=-4x^2$

Therefore, the equation of the parabola given in the picture is option D. $y=-4x^2$
