Given the following factorable quadratic relations, sketch their graphs (include x-intercepts, y-intercept, and vertex). Show all work.
a. y = -x2 + 7x + 18
b. y = 2x2 + 17x + 21

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3
