Question

Which of the following represents the vertex and x-intercepts of the function given below?

y = x^2 + 8x + 12

A. Vertex: (2,6)
Intercepts: x = 6, 2
B. Vertex: (4,60)
Intercepts: x = 6, -2
C. Vertex: (-4,-4)
Intercepts: x = -6, -2
D. Vertex: (4,-4)
Intercepts: x = -4, -3

Answer 1

correct me if im wrong but I got C!

Answer 2

y = x^2 + 8x + 12
y = (x + 4)^2 -16 +12
y = (x + 4)^2 - 4
Vertex (-4, -4)
x -intercept is when y = 0, (-2, 0), (6, 0)
y - intercept is when x = 0, (0, 12)
