The vertex of a parabola is (-2, -20), and its y-intercept is (0, -12). the equation of the parabola is y = x2 + x +

Step-by-step explanation:

To write the quadratic equation, begin by writing it in vertex form  

Where (h,k) is the vertex of the parabola.

Here the vertex is (-2,-20). Substitute and write:

To find a, substitute one point (x,y) from the parabola into the equation and solve for a. Plug in (0,-12) the y-intercept of the parabola.

The vertex form of the equation is .

You can convert this into standard form by using the distributive property.
