Find the equation, in standard form, of the parabola going through (-2,4),(0,-4), and (2,4). What is a + b + c?. There is no visual. I NEED THIS ASAP

Step-by-step explanation:

Parabola is the graph of a quadratic function:

Given points:

Substituting the points:

1.

2.

3.

Considering c = -4 in the other equations:

and

Comparing the above two equations:

Then finding a:

So we have equation:

and

answer:     true

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
