  11. Problem #2: Graphing a Real-World Function Rule a) The function rule C = 12.5h + 30 represents the total cost of renting a truck for h hours. What is a reasonable graph of the function given that the daily limit is 12 hours.

  12. Problem #2: Graphing a Real-World Function Rule b) The function rule W = 146c + 30,000 represents the total weight of a concrete mixer truck that carries cubic feet of concrete. If the capacity of the truck is about 200 , what is a reasonable graph of the function rule?

  13. Problem #2 Got It? The function rule W = 8g + 700 represents the weight of a hot tub that contains gallons of water. What is a reasonable graph of the function rule, given that the capacity of the spa is 250 gal?

  14. Continuous Graph: A graph that is unbroken Discrete Graph: Composed of distinct, isolated points KEY Vocabulary

  15. Problem #3: Identifying Continuous and Discrete Graphs a) A local cheese maker is making cheddar cheese to sell at a farmer’s market. The amount of milk used to make the cheese and the price at which he sells the cheese are shown. Write a function for each situation. Graph each function. Is the graph continuous or discrete?

  16. Problem #3: Identifying Continuous and Discrete Graphs b) The amount of water w in a wadding pool, in gallons depends on the amount of time t, in minutes, the wadding pool has been filling, as related by the function rule w=3t. Graph the function. Is the graph continuous or discrete?

  17. Problem #3: Identifying Continuous and Discrete Graphs c) Megan buys eggs at the supermarket for $1.75 per carton. The cost is a function of the number of cartons bought. Graph the function. Is the graph continuous or discrete?
