The polynomial function y = -0.005x4 + 0.05x3 – 0.086x2 – 0.04x + 2.52 represents the fluctuating gas price (in dollars per gallon) in a city over the course of 6 years. Calculate the average rate of change from year 0 to year 2, and then calculate the average rate of change from year 3 to year 6.

Part a) The average rate of change is -0.052

part b) The average rate of change is 0.311

Step-by-step explanation:

we have

we know that

the average rate of change is equal to

Part a) Calculate the average rate of change from year 0 to year 2

In this problem we have

Substitute

Part b) Calculate the average rate of change from year 3 to year 6

In this problem we have

Substitute

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
