Answer:
D. Vertex (1, -25); intercepts x = -4, 6
Step-by-step explanation:
Vertex
x = -b/2a
x = - (-2)/2(1)
x = 2/2
x = 1
y = 1^2 - 2(1) - 24
y = 1 - 2 - 24
y = -25
Vertex (1, -25)
x-intercepts when y = 0
x^2 - 2x - 24 = 0
(x - 6)(x + 4) = 0
x - 6 = 0; x = 6
x + 4 = 0;x = -4
Answer
D. Vertex (1, -25); intercepts x = -4, 6
