Answer

Explanation:

Step1: Understand function notation

In a function $h(t)$, when we evaluate $h(a)$ (here $a = 3.2$), $t$ is the independent - variable representing time and $h(t)$ is the dependent - variable representing height.

Step2: Interpret $h(3.2)$

Since $t$ represents the time after the rock is propelled and $h(t)$ is the height function, $h(3.2)$ represents the height of the rock 3.2 seconds after it is propelled.

Answer:

the height of the rock 3.2 seconds after it is propelled
