Nevin and Bruce are climbing a mountain. The mountain has two trails. One gets drastically
steeper near the top, and the other is more gradual. Nevin and Bruce take different trails and
race up the mountain.
a. The function that represents Bruce's elevation in feet over time in hours is an exponential
function that starts at 1,505 feet. The first hour, his elevation change is six feet. Each
successive hour, his average elevation change for the hike becomes six times the previous hourly elevation change. Write a function for Bruce’s elevation. Is it an exponential growth or an exponential decay function?
