a The function c(t) is defined as the number of costumers in a restaurant t hours after 8 A.M. Let's interpret the given statement.
c( 0)= 0
The above tells us the number of customers 0 hours after 8 A.M. is 0. Therefore, we can say there are no customers at 8 A.M.
b Let's continue with the second statement.
c( 3)= c( 8)
The above states that the number of customers 3 hours after 8 A.M., and the number of customers 8 hours after 8 A.M. are the same. This means that the number of customers at 11 A.M. and 4 P.M. are the same.
c Let's consider the given statement.
c( n)= 29
The above says that after n hours, the number of customers is 29.
d Now, we will examine the last statement.
c( 13)< c( 12)
The above states that the number of customers 13 hours after 8 A.M. is less than the number of customers 13 hours after 8 A.M. This means that at 9 P.M. there are less customers than at 8 P.M.
