the coefficient of is positive, therefore, this quadratic has a minimum value. It occurs at the vertex.

To find the vertex of a quadratic of the form , we use the formula:

Thus the vertex is the point

Use the formula i mentioned above

Find the coordinates of the vertex for the parabola defined by the given quadratic function.f(x) = -x2 - 8x - 4
