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

probability for j is 1/4

while

a is 1/6

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
