SOLUTION: Find the vertex of the graph of the quadratic function.
f (x)=-x^2-10x-7
I'm not sure what to do here. Could you please tell me where to start and what I'm doing? Thanks

You can put this solution on YOUR website! Find the vertex of the graph of the quadratic function.
f (x)=-x^2-10x-7
the formula of the vertex is V=(-b/2a,f(-b/2a)) so
V=(-5,f(-5))=(-5,18)
