Hi,

Note: the vertex form of a parabola, y=a%28x-h%29%5E2+%2Bk where(h,k) is the vertex

f(x)= -(x+8)^2 -3



V(-8,-3), a = -1, -1<0, Parabola open downward.  Vertex is a max point

x = -8 is the line of symmetry. Maximimum value for the functions is -3

The vertex = (-8,-3)

The line of symmetry = x = -8

The minimum or maximum value= -3

Is this maximum or minimum  max value
