I think you mean the zeros of the function.
The average of the zeros would be the x-coordinate of the vertex.

Example:
f%28x%29=%28x-2%29%28x-4%29
has zeros at x=2 and x=4.
When you convert to vertex form, y=a%28x-h%29%5E2%2Bk,
f%28x%29=x%5E2-4x-2x%2B8
f%28x%29=x%5E2-6x%2B8
f%28x%29=%28x%5E2-6x%2B9%29%2B8-9
f%28x%29=%28x-3%29%5E2-1
The vertex is located at (3,-1).
