# Graphing y=a/(x-b)+c

Lesson 5 of 10

## Objective: SWBAT choose inputs to graph functions in the form y=a/(x-b)+c and identify the asymptotes of these functions using their data tables. Students will be able to write approach statements to describe the behavior of these functions near their asymptotes.

## Big Idea: Students develop the tools to graph rational functions by choosing inputs that reveal the behavior of vertical and horizontal asymptotes. Students describe this behavior using approach statements.

I use these 4 closing questions (Exit Ticket 5) differently depending on how the lesson has proceeded. Typically, I distribute the questions on a half-sheet of paper. I give students 5 minutes or so to discuss the questions with their partner or group and to attempt to answer them. Then, I facilitate a brief whole-class discussion, during with I make sure that somebody (me or a student) clearly articulates the key ideas (Exit Ticket Sample Responses).

At this time, I usually project the questions and write the key ideas on the projected copy during the discussion. I then give students a few more minutes to write their best answers to the questions. I read student responses as they leave the classroom and they can either keep their answers or give them to me.
