3. Function (input/output) Tables
Make an input/output table for the function
y = 3x + 1.5
Use 0, 1, 2, 3 as the domain
Input (x)
Output (y) 1 2 3

5. Finding Functions in Real Life
The Gwinnett County Fair charges $4.00 per vehicle and $1.50 for each person in the vehicle. If you represent the total charge as C as a function of the number of persons (p), what would it look like as a function and as a table?
Function Form
TABLE FORM P C 1
5.50 2
7.00 3
8.50 4
10.00
People charge + vehicle charge = cost
$1.50 per person + $4.00 = total cost
Let p = number of people c = total cost
1.50p + 4 = C
