Question

HELP ME PLS ASAP What are the vertex and x-intercepts of the graph of the function given below?

y = x2 - 2x - 48
O A. Vertex: (1, -49); x-intercepts: (8,0) and (-6,0)
B. Vertex: (0,0); x-intercepts: (-4,0) and (6,0)
C. Vertex: (1,-40); x-intercepts: (6,0) and (7,0)
O D. Vertex: (-1, -21); x-intercepts: (6,0) and (4,0)

Answer 1

I know this isnt helpful now but the answer is A

Explanation:

Just solving for the intercepts:

y = x^2 - 2x - 48

Factor

(x + 6) (x - 8)

equal both problems to zero

x + 6 = 0

x - 8 = 0

solve

x = 8, and -6
