Answer:
Option d. h(t) = 2000t + 800
Explanation:
Juan is hiking up a mountain starting at an elevation of 800 feet.
Every hour he gains an elevation of 2000 feet.
So we have to find a function for h(t) where is the time and h is the height.
Since Juan gains height in 1 hour = 2000 ft.
therefore, height gained in t hours = 2000 ft.
He started hiking from 800 ft so total height after t hours will be 2000t + 800
In the form of a function h(t) = 2000t + 800
Option d. is the answer.
