Question 397101: find the vertex, the line of symmetry, and the maximum or minimum value of f(x). Graph the function.
f(x)= -(x+9)^2-4
the vertex is?

The vertex is the point (-9, -4).
Line of symmetry is x = -9.
Since a = -1 < 0, the parabola opens downward, and the function has a maximum value of -4 (the y-coordinate of the vertex).
