Function or Not Domain Range

Which is the set of all y-values or the outputs?

• Domain

• Range

• Relation

• Function

What is the most accurate definition of function?

• Has inputs and outputs

• Every input has only ONE output

• Inputs have different outputs every time

• x-values and y-values

Answer explanation

Think about a vending machine: inputs are "buttons", outputs are what the vending machine gives you
