"each month of the year is mapped to the possible number of days per month." is this a function? if so, what is the domain and range?

Step-by-step explanation:

This is not a function because the month of february has different days depending on the year.   Thus, you'd have 1 input (february) that would yield more than 1 output (28,29).  

The given relation is not a function.

Step-by-step explanation:

It is given that "Each month of the year is mapped to the possible number of days per month."

In means input value is month name and output value is number of days in that month.

A relation is called function if each input value has unique output value.

We know that the number of day in feburury is 28 and 29 (in leap year).

For same input feburury we have two outputs 28 and 29.

Therefore, the given relation is not a function.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

y + 11 = (1/4)(x + 16)
