You can put this solution on YOUR website! A local parking garage charges $5.00 for the first hour plus $1.50 for each additional hour or part of an hour. Write a relation as a set of ordered pairs in which the x-value represents the number of hours and the y-value represents the cost for x hours. Use a domain of 1,2,3,4,5. Is this relation a function? Explain
-------------
y = 5 + 1.5(x-1) = 1.5x + 3.5
(1,5)
(2,6.5)
(3,8)
(4,9.5)
(5,11)
========================
The relation is a function because each domain value has one cast associated with it.
