## Lesson 1.6

OBJ: To Represent Functions as Rules and Tables

### A Function consists of:

• a set called the domain containing numbers called inputs and a set called the range containing numbers called outputs.

• a pairing of inputs with outputs such that each input is paired with exactly one output.

• Functions can be shown through tables or mapping diagrams.

• An output may be paired with more than one input, but no input is paired with more than one output.

### More With Functions

• A function may be represented using a rule that relates one variable to another. The input variable is called the independent variable. The output variable is called the dependent variable because its value depends on the value of the input variable.
