Find the average rate of change for f(x)=x+6 over the interval [4,8]
Accepted Solution
A:
Solve for f(x) using both 4 and 8:f(x) = 4+6 = 10f(x) = 8+6 = 14Find the difference between the answers:The difference between the two answers is 14-10 = 4Find the difference between the interval:The difference between 4 and 8 is: 8-4 = 4The rate of change is the change in the answers over the difference in the interval:The rate of change is 4/4 = 1
