Function Machines & Input/Output Tables

Function Machines & Input/Output Tables

​Later on in this unit...

What is an Input/Output table?

• represents values that follow a rule or pattern (example: subtract 1)

• The input side (x) is the number that you start with and perform the rule with (example: start with 66, subtract 1)

• The output side is the solution once you applied the rule (example: 66 - 1 = 65 so the output is 65)

Remember - x is INPUT, y is OUTPUT
