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:
