Interpreting the Graph

1.3 – Taxi Fares, Time Payments, and Step Functions What patterns of change can be modeled by functions called step functions?

Launch Video https://dashweb.pearsoncmg.com/main.html?r=24369&p=642

Taxi Cab Fares What do you know about taxi fares? What does the price of a taxi fare depend on?

Problem 1.3 (pg. 12) A and B Go ahead and try it out with your tablemates! Draw the tables and graphs

Problem 1.3 A Answer Key

Problem 1.3 B Answer Key integers which are multiples of 10 up to 240.

Summary Why is a step function an appropriate name for this kind of graph? Can you think of a function that would describe how this graph behaves? What did you do about the end points of the horizontal steps in the taxicab function?
