Question

Determine whether each relation is a function. Write yes or no.

Step-by-Step Solution

Answer

No, the given relation is not a function.

Step 1 – Definition of function.

A relation is a function if each element of the domain is paired with exactly one element of the range.

A relation is not a function if there exist an element in the domain paired with more than one element of the range.

Step 2 – Given information.

The given graph of a relation is:

Step 3 – Check whether the relation is function or not.

The set notation of the given relation is $\left\{\left(-1,4\right),\left(2,2\right),\left(2,3\right),\left(3,1\right)\right\}$.

This relation is not a function because 2 in the domain is paired with both 2 and 3 in the range.

 

Thus, the required answer is no because the given relation is not a function.
