Function: Average Rate of Change

Easy

(Originais Teachy 2023) - Question Easy of Math

An environmental scientist is studying the population of a specific type of tree in a forest over a span of years. He discovered that the function P(t) = 3t² - 2t + 5, where P is the tree population and t is the time in years, represents his findings. From the 2nd to the 5th year, can you determine the average rate of change of the tree population?
a.
The average rate of change of the tree population from the 2nd to the 5th year is 20 trees per year.
b.
The average rate of change of the tree population from the 2nd to the 5th year is 19 trees per year.
c.
The average rate of change of the tree population from the 2nd to the 5th year is 17 trees per year.
d.
The average rate of change of the tree population from the 2nd to the 5th year is 22 trees per year.
e.
The average rate of change of the tree population from the 2nd to the 5th year is 15 trees per year.

A gardener has planted two trees: a cherry tree and an apple tree. She observed that both trees grew at different rates over time. She recorded the height of the cherry tree as a function f(x) and the height of the apple tree as a function g(x), where x represents the number of years since the trees were planted. If she has recorded their heights over a period of 6 years, how would you determine the average rate at which the height of each tree changed over this time interval?

Suppose you are hired to work on a project to construct a new bridge. This bridge is designed to have its height change at a constant rate over time during the construction. On the first day of construction, the height of the bridge is 2 meters. After 5 days, the height of the bridge is 12 meters. Calculate the average rate of change of the height of the bridge from the first day to the fifth day.
