Lesson Plan : Inverse Functions

**Teacher Name: **
| Mr. Cochran |

**Grade:**
| Grade 9-10 |

**Subject:**
| Math |

**Topic: **
| California Standard (24): Students solve problems involving functional concepts, such as composition, defining the inverse function and performing arithmetic operations on functions. |

**Content: **
| Inverse Functions: Vocabulary
Inverse relation -
Inverse function - |

**Goals: **
| Goal #1 - Find Inverse of linear functions.
Goal #2 - Find Inverse of nonlinear functions. |

**Objectives:**
| Have students be able to describe the steps for finding the inverse of a relation. |

**Materials:**
| Overhead projector, graphing calculator, and Smart Board. |

**Introduction:**
| Lesson Opener Activity. Using transparency 7-4 and have students match each composition of functions on the left with a simplified expression on the right to reveal something you might say while riding a roller coaster. |

**Development:**
| Finding an Inverse Relation. Find an equation for the inverse of the relation y = 3x - 1. Using notetaking worksheet along with the Smart Board for student assistance. |

**Practice:**
| Verifying Inverse Functions. Verify the inverse function of y = 3x - 1. |

**Accommodations:**
| Use the graphing calculator to show inverse relationships. |

**Checking For Understanding:**
| Use problems 1-3 of the student notetaking worksheet to allow checking for understanding inverse functions. |

**Closure:**
| Question to students: Describe the steps for finding the inverse of a relation. |

**Evaluation:**
| Day after the lesson. Homework quiz on inverse relations. |

**Teacher Reflections:**
| Mr. Cochran and Mr. Smith will reflect on todays lesson. |
