My Instructional Unit


Graphing Relations and Functions

Chapter 5

Here are the things that should have been covered before you should do this unit:

Solving an equation for a specific variable. (Examples)

Evaluating algebraic expressions. (Examples)

Finding and extending patterns in number sequences. (Examples)

Finding the median of a set of data. (Examples)


This unit is on relations and functions, two very important topics to be developed.


At the end of this sections your students should be able to do the following:

Graph ordered pairs, relations, and equations

Solve problems by making a table

Identify the domain, range, and inverse of a relation

Determine if a relation is a function

Write an equation to represent a relation

Calculate and interpret the range, quartiles, and interquartile range of a set of data
