Answer:
The vertex form of a quadratic function:
(h,k) - the coordinates of the vertex
If a>0, then the parabola opens upwards, so the vertex is the minimum of the function.
If a<0, then the parabola opens downwards, so the vertex is the maximum of the function.
Answer:

Step-by-step explanation:
If we have a product function y, in the following format

This function has the following derivative

In this problem, we have that:

So

The derivative of the function is:




The value of y should be 8
