Aparabola has a vertex at (-1, 0) and opens down. what is the equation of the parabola?

y = -x^2 - 1
y = -(x - 1)^2
y = -(x + 1)^2

C.

Step-by-step explanation:

We have been given that a parabola has a vertex at (-1, 0) and opens down. We are asked to find the equation of the parabola.

We know that the vertex form of parabola is in form: , where, point (h,k) is the vertex of parabola and sign of 'a' determines whether parabola opens upwards and downwards.

Since the vertex of our given parabola is at (-1,0) and it opens downwards, so the leading coefficient will be negative.

Therefore, the equation of the parabola is and option C is the correct choice.
