Find the equation of the quadratic function with vertex (-2,18) passing through (-5,0)?

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

It's been given the vertex of the parabola as (-2,18):

Now substitute the point (-5,0) and find the value of a:

Operating:

Solving for a:

a = -2

Thus, the equation of the quadratic function is:
