Compare the rates of change.

• The rate of change of item II is greater than the rate of change of item I.

• The rate of change of item I is greater than the rate of change of item II.

• Both items have the same rate of change.

Determine whether the following functions are increasing or decreasing.

• The function in item I is increasing, and the function in item II is decreasing.

• Both functions are increasing.

• The function in item I is decreasing, and the function in item II is increasing.

• Both functions are decreasing.

Compare the initial values of the functions.

• Both functions have the same initial value.

• The initial value of item I is greater than the initial value of item II.

• The initial value of item II is greater than the initial value of item I.
