An object is fired upward from the top of a 200 ft. tower at a velocity of 80 ft/sec. The height of the object, h(t), is modeled by the function h(t) = -16t2 + 80t + 200, where t represent the time in seconds.

    Which time is specified? I bet you are left to use the formula to calculate the height of the object at certain time following the launch

    Type that into desmos calculator. You should get a vertex of (2.5,300)

    It's saying that after 2.5 seconds from the launch the height of the object reaches 300m
