1. 1. What are the coordinates of the vertex of the
parabola defined by f(x) = -3(x + 4)2 - 5?

2. 2. A ball is thrown straight up t an initial velocity
of 54 feet per second. The height of the ball t
seconds after it is thrown is given by the
2
formula h(t) = 54t - 12t . How many seconds
after the ball is thrown will it return to the
ground?

(2, -3) and passes through the point (-1, 1) is

4. Solve x2 - x = 2
