This is a parabola that opens upward, and the axis of symmetry for such a graph in the form of y=ax%5E2%2Bbx%2Bc will always be x=-b%2F%282a%29.

In the case of y=x%5E2%2B6x+%2B5, the axis of symmetry will be x=-6%2F2=-3

The graph looks like this, using a graphing calculator, or this fantastic "algebra.com" calculator:
