Question

Juan is hiking up a mountain starting at an elevation of 800 feet. Every hour, he is 2000 feet higher in elevation.

Which function, h(t), where t is time in hours, represents Juan's height over time?

1. h(t)=2800t
2. h(t)=800t+2000
3. h(t)=2000t
4. h(t)=2000t+800

Answer 1

4. h(t)=2000t+800

Explanation:

800 is his starting elevation we dont not multiply it

every hour he gains 2000ft in elevation and t shows the hours 2000ft * t (hours) + 800
