Find the vertex, the y-intercept, and the x-intercepts (if any exist), and graph the function.r(x) = x2 + 6x + 9

Question

A.

Vertex (-3, 0)
x-int = (-3, 0);
y-int = (0, 9)
B.

Vertex (0, 9)
no x-intercepts;
y-int = (0, 9)
C.

Vertex (3, 0)
x-int = (3, 0);
y-int = (0, 9)
D.

Vertex (0, -9)
x-int = (-3, 0),
(3, 0); y-int = (0, -9)
