I think you mean "quadratic function." That's because , is, in fact, a quadratic function. The Quadratic Formula is something else entirely.

Given a quadratic function of the form:

The -coordinate of the vertex is . The -coordinate of the vertex is the value of the function at that -value.

So: , and . Hence the vertex is at
