A local skateboard park has a structure shaped like a parabola dug into the ground. The structure can be represented by the quadratic function shown on the graph where x represents the horizontal distance in feet and y represents the depth underground in feet.

Charlie must find the domain of the graph.

La'Tisha is standing in the pool and hits a beach ball to her sister. The function h(t) = -16t² - 32t represents the height of the ball above the water over time, t.

Choose the correct maximum

• maximum = 16

• maximum = 1

• maximum=2
