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 8A.M., and the number of customers 8 hours after 8A.M. are the same. This means that the number of customers at 11A.M. and 4P.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 8A.M. is less than the number of customers 13 hours after 8A.M. This means that at 9P.M. there are less customers than at 8P.M.
