Ответ:
x intercepts: (-1, 0) and (5, 0)
vertex: (2, 9)
axis of symmetry: x = 2
Step-by-step explanation:
The x intercepts are where y = 0.
0 = -(x + 1)(x − 5)
x = -1, x = 5
So the x intercepts are (-1, 0) and (5, 0).
The x coordinate of the vertex is halfway between the x intercepts.
x = (-1 + 5) / 2
x = 2
So the vertex is at (2, 9).
The axis of symmetry passes through the vertex.
x = 2
