Mr. Grannen was launching a rocket off of his 8.2-foot tall porch. The graph shown models the path of the rocket over time (in seconds). Interpret the vertex of the parabola.

• The rocket launched off the porch from 8.2 feet.

• After 2 seconds the rocket was 12 feet off the ground.

• The rocket landed in 5.5 seconds.

• After 4 seconds the rocket was 8.2 feet off the ground.

Choose the best description of the parabola represented by the following equation:

y = - (x + 2)(2x - 3)

• The parabola is concave down, has a y-intercept at (0, 6), and has x-intercepts at

       (2, 0) and (-1.5, 0).

• The parabola is concave up, has a y-intercept at (0, 6), and has x-intercepts at (-2, 0) and (1.5, 0).

• The parabola is concave down, has a y-intercept at (0, 6), and has x-intercepts at

       (-2, 0) and (1.5, 0).
