Input/Output Tables

Front

What is an input/output table?

Back

An input/output table is a mathematical tool used to show the relationship between input values and output values based on a specific rule or function.

Front

What does it mean to 'multiply by 3'?

Back

To 'multiply by 3' means to take a number and increase it by a factor of three. For example, if the input is 2, the output will be 2 x 3 = 6.

Front

How do you find the missing input in an input/output table?

Back

To find the missing input, you can use the output value and the rule of the function to work backwards.

Front

What is a function rule?

Back

A function rule is a mathematical expression that defines the relationship between input and output values.

Front

If the rule is 'add 1', what is the output when the input is 5?

Back

The output is 6, because 5 + 1 = 6.

Front

What is the output when the input is 10 and the rule is 'multiply by 2'?

Back

The output is 20, because 10 x 2 = 20.

Front

What are the steps to complete an input/output table?

Back

1. Identify the rule. 2. Apply the rule to each input to find the corresponding output.

Front

What is the output for an input of 4 if the rule is 'add 3'?

Back

The output is 7, because 4 + 3 = 7.

Front

How can you check if a function rule is correct?

Back

You can check if a function rule is correct by applying it to known inputs and outputs and verifying that they match.

Front

What is the missing number if the input is 3 and the output is 9 with the rule 'multiply by 3'?

Back

The missing number is 3, because 3 x 3 = 9.
