Question

I don't know how to start to solve this.

The "vertex" of the graph of a quadratic function is the point that corresponds to the minimum (or maximum) output value.

a. Suppose f(x)=(10x−5)(7x−8). Determine the vertex of the graph of f.

b. Suppose g(x)=x2−82. Determine the vertex of the graph of g.

c. Suppose h(x)=3x2+11x+7. Determine the vertex of the graph of h.
