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

 The function  represent a downward parabola with vertex 

(-8, -3), line of symmetry x=-8, and maximum value y=-3. See the graph below:
