The amount of a retiree's benefit depends on the retiree's lifetime earnings, the person's full retirement age, and the age at the time of retirement. The following function gives the annual6 benefit in dollars for a person retiring in 2009 at ages 62 through 70 with a full retirement benefit of $12,000 at full retirement age of 66.

B = {600a - 28,200   62 ≤ a <64

804a - 41,064    64≤ a <67

960a - 51,360   67 ≤ a ≤ 70

a) Graph the benefit function.

b) What is the annual benefit for a person who retires at age 64?

c) At what age does a person receive an annual benefit of $14,880?

d) What is the average rate of change of the benefit for the ages 62 through 63? Ages 64 through 66? Ages 66 through 70?
