Determine the vertex of:
y = -3x2-6X+9

#12 find the value of x. #13 find the value of the variable.

Given the conditional statement, match the following. conditional statement: if two lines intersect, then their intersection is one point.

The function ƒ is defined by ƒ(x) = (x + 3)(x + 1). the graph of ƒ in the xy-plane is a parabola. which interval contains the x-coordinate of the vertex of the graph of ƒ?
