Select one:

a. a linear function

b. an exponential function





Question 5

In a certain apple plant, the amount of apples shipped annually is increasing by 15%15% of the amount from the year before. This relationship can be described by:



Select one:

a. a linear function

b. an exponential function



Question 6

In a certain production plant, the annual production amount is decreasing by 10%10% of the amount from the year before. This relationship can be described by:



Select one:

b. an exponential function

c. both a linear and exponential function

Answer 1

No function is both linear and exponential!
If there is a constant amount (say, m) added or subtracted, that is a linear function (with slope m)
If there is a constant multiplication factor, that is an exponential function.
