    Answer:

    Step-by-step explanation:

    The rock’s height is increasing in the interval from 0 seconds to 3 seconds.

    At time 0 the rock starts moving upward from 52 foot until it reaches 180 foot height (time 3 seconds). Then the rock starts to descend, which means that the height starts to decrease.
