Unit 3: Introduction to Functions


Before 8th grade you may remember working with an input-output table.   In 8th grade, you will begin to call relationships between inputs and outputs functions. The big idea is that a function uses a rule where each input is assigned to exactly one output.  You will learn how to identify and compare functions in different forms, such as a table, graph, equation or a verbal description.  You will also be able to tell the difference between linear and non-linear functions in the different forms and recognize the equation y = mx + b as a representation of a linear function.
