the function h(t)= - 16t² + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot. what does h(3.2) represent? the height of the rock 3.2 seconds before it reaches the ground the time it takes the rock to reach the ground, or 3.2 seconds the time it takes the rock to reach a height of 3.2 meters the height of the rock 3.2 seconds after it is propelled
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
