Answer:
The vertex is at (1, -108).
Step-by-step explanation:
We have the function:

And we want to find its vertex point.
Note that this is in factored form. Hence, our roots/zeros are <em>x</em> = 7 and <em>x</em> = -5.
Since a parabola is symmetric along its vertex, the <em>x-</em>coordinate of the vertex is halfway between the two zeros. Hence:

To find the <em>y-</em>coordinate, substitute this back into the function. Hence:

Therefore, our vertex is at (1, -108).
