##### Examples
###### Lessons
1. Solve for the Function Table's Missing Variables
Use the rule to complete the function table:

2. Solving for Function Table Rules
Write the rule for the function table
• Write the one-step rule as a formula with a variable

3. Using Two-Step Rules to Complete Function Tables
Use the two-step rule to complete the function table.

4. Solving for Two-Step Rules in Function Tables
Write the two-step rule for the function table.
1. $output = (m) input \pm b$
2. $output = (m) input \pm b$
3. $output = (m) input \pm b$
4. $output = (m) input \pm b$
