Answer:
vertex: (-5, 2)
axis of symmetry: x = -5
Step-by-step explanation:
The vertex for a downward-opening parabola is the absolute maximum. In this case, the vertex is (-5,2) because the range does not exceed y=2 when x=-5.
The axis of symmetry is a line that divides the parabola into two halves by a vertical axis. This means that the axis of symmetry is x=-5
