Hi,
Using the vertex form of a parabola,  where(h,k) is the vertex
f(x) = -(x+8)^2-3 |V(-8,-3), a = -1 <0 ,parabola opens downward, vertex a max Pt
x = -8, line of symmetry

You can put this solution on YOUR website! The function  represent a downward parabola with vertex
(-8, -3), line of symmetry x=-8, and maximum value y=-3. See the graph below:
