Which point is the vertex of the quadratic function

C. (4, 3)

Step-by-step explanation:

The vertex of a quadratic function is (h, k). Since this equation is already in vertex form: a(x - h)^2 + k, we can find the vertex just by looking at the equation.

h = 4, k= 3, so the vertex is (4, 3).

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
