Vocabulary

100

What is a function?

The relation that assigns exactly one input and one output value.

200

What is the function rule?

The thing that describes the relationship between the input and output.

300

What is a function table?

The table that you can organize the input and output, and the function rule in.

400

What is an independent variable, and why?

The input, because it does not rely on anything.

500

What is a dependent variable, and why?

The output, because it depends on the input.
