Functions and Relations

Functions and Relations

Unit 4: Functions

​

​

Today I am learning about functions

I’ll know I am successful when I can:

· know that a function is a rule with exactly one output for each allowable input.

· know that if a rule has exactly one output for each allowable input, then the output depends on the input

​Instructions:

​You are about to watch a brief video on Functions and Relations. You will need to complete the following:

​1. Record the definitions of the vocabulary words.

​2. Under the definitions, Draw a T chart and record examples of Functions and Relations. See the Example.
