Problem #12

ERROR ANALYSIS: Describe and correct the error in determining whether the relation is a function.

• In order for a relation to be a function, each output must be paired with exactly one input. So, the relation is not a function.

• In order for a relation to be a function, each input must be paired with more than one output. So, the relation is a function.

• In order for a relation to be a function, each input must be paired with exactly one output. So, the relation is not a function.
