U3 – Rational Functions

Unit 3

Day Lesson Title Exercises
1 & 2 3.1 – Reciprocal of a Linear Function

  • Students are to complete the anticipation guide prior to the lesson.Complete examples with the class. As an achievement check, students will sketch a graph of a rational function (this will be used to complete a performance wall the next class day).
  • Three solutions will be previously made up on chart paper. The students will decide on which is the best, worst, middle. As a class discuss how to make the worst the middle, and the middle the best. Discuss all the key properties of the graphs.
