Answer:

x = -6 or -4

Explanation:

Maybe you want to know the x-intercepts. They are found by ...

0 = (x +5)² -1 . . . . . divide by -4

1 = (x +5)² . . . . . . . add 1

±√1 = x +5 . . . . . . square root

-5 ± 1 = x . . . . . . subtract 5

x = -6 or -4

__

The vertex is (-5, 4). The parabola opens downward, so the vertex is a maximum. The range of the function is (-∞, 4]. The vertical scale factor is -4, so the graph will appear narrower than that of the parent function.
