Question

Emme bought cashews that cost $3.42 per pound. Which of the following does this situation represent?

neither a relation nor a function

a function only

a relation only

both a relation and a function

Answer 1

Both a relation and a function

Explanation:

A relation is a set of one or more ordered pairs.

A function is a relation in which each element of the domain is paired with EXACTLY one element of the range.

In this case, the cashews cost $3.42 per pound. This means that it is impossible for a certain weight of cashews to have two different prices.

Therefore, the situation represents both a relation and a function.
