3.1 Function Practice

What is the domain?

• the set of all x-values
• the set of all y-values

What is the range?

• the set of all x-values
• the set of all y-values

What is a function?

• relation that pairs each domain with exactly 1 range
• relation that pairs each range with exactly 1 domain
• relation that pairs each domain with more than 1 range
• all the x-values are the same

Function?

• This graph is a function

• This graph is not a function

Function?

• This graph is a function

• This graph is not a 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.
