Answer:  (-7, -4)

========================================

Explanation:

The general equation y = a| x-h | + k has the vertex (h,k)

Rewrite the original function in this form to get f(x) = -1|x - (-7)| + (-4) and we see that h = -7 and k = -4

So that's why the vertex is (h,k) = (-7, -4)

The V shape graph opens downward meaning that the vertex (-7, -4) is at the highest point. The graph is shown below. I used GeoGebra to make the graph.
