Step-by-step explanation:
The relationship given:
h(t) = 3.5t + 48See the graph attached. It includes the endpoints as described below, considering h = 48 as lowest and h = 252 as highest points of the function.
The t- coordinates of the respective h- points are:
3.5t + 48 = 483.5t = 0t = 0 secand
3.5t + 48 = 2523.5t = 204t = 204/3.5t ≈ 58.29 secThe domain:
[0, 58.29]The range:
[48, 252}
