Functions - Review

What is the vocabulary term that describes this: f(x) ?

• f of x
• functions
• function rule
• function notation

All of the x values or inputs are called what?

• Domain
• Range
• Relation
• Function

• Function
• Not a Function

Is this table a function or not a function? 

• Function
• Not a Function 

All of the y values or outputs 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.

Identify the domain of the following relation:

• -6, 14, 2, 28
• (-6,14), (0,32), (2,38), (4,44)
• -6, 0, 2, 4
• 14, 32, 38, 44

If my function rule is  x÷3, what is the OUTPUT if the input is 12?

• 9
• 4
• 3
• 36
