Introduction to Functions

What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values

Is this mapping a function or not a function? 

• Function
• Not a Function

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function

All of the x values or inputs are called what?

• Domain
• Range
• Relation
• Function

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Is this table a function or not a function? 

• Function
• Not a Function

• y = x²
• y = a⋅b^x
