What are the vertex and x-intercepts of the graph of the function given below?
y = x – 2x – 24
O A. Vertex: (1, -21); x-intercepts: (6, 0) and (4,0)
B. Vertex: (0, 0); x-intercepts: (-4, 0) and (6, 0)
C. Vertex: (1, -25); x-intercepts: (6, 0) and (-4, 0)
OD. Vertex: (7, 5); x-intercepts: (6, 0) and (8,0)

Respuesta :

Answer:

C

Step-by-step explanation:

I think that first x should be x^2

y = x^2 - 2x - 24 =   ( x-6)(x+4)        at the x - intercepts , the equation = 0

                  so the intercepts = 6, 0   and -4,0

         vertex will be between these points where x = 1    then y = -25
