Relations Functions Range Relations vs Functions

Is this graph a function or not a function? 

• Function

• Not a Function

Let 𝐹 be a set of ordered pairs such that {(−3,5),(3,0),(2,2)}. Which of the following statements about the relation is true?

• The relation is a function because no value in the domain goes to multiple values in the range.

• The relation is a function because all values in the range are different.

• The relation is not a function because one value in the domain goes to multiple values in the range.

• The relation is not a function because there is an ordered pair where the domain is equal to the range.

Is the relation above a function?

• Yes, because it doesn’t show any repeating 𝑥 values in the domain.

• Yes, because every 𝑦 value in the range is different.

• No, because one 𝑥 value in the domain goes to multiple different 𝑦 values in the range.

• No, because there is an 𝑥 value in the domain that is equal to a 𝑦 value in the range.
