In each of the following situations: 1) Identify the dependent and independent variable 2) Write it out using “is a function of” 3) Write a rule using function notation 4) Find f(5) and tell what it means in the context of the situation. 1. The initial fee for placing a color ad in the newspaper is $20. Each line of the ad costs an additional $7. Cost vs. number of lines
2. A cheese pizza costs $7. Each additional topping is $2. Cost vs. Number of toppings

5. Give at least 3 examples of functions we have explored so far this year (staircase towers etc). Which variable is the independent variable and which is the dependent variable? Rewrite these equations using function notation to show the relationship.
