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:

Answer:

Step-by-step explanation:
we have
-----> equation A
-----> equation B
To find out (V of r)(t) substitute equation B in equation A
