examine the mapping diagram. the first set is the months of the year and the second set is the possible number of days per month. is this relation a function? explain.

The relationship is not a function.

Step-by-step explanation:

A relation is a function if and only if for each value of the variable x there exists a single value of f(x).

This means that if for a single value of x there is more than one value of y  then the relation is not a function.

The variable Months on the axis of abscissas and the variable days on the axis of the ordinates.
