Step 1

Assume that, the domain of the function is a set of all people whose birthday is same to you (month and date, not necessarily year) and codomain is a birthday.

Here, the number of the people in the domain x is finite and that assign to a single birthday in the codomain f(x).

Step 2

Now, draw the graph for the finite number of the people, whose share the same birthday (month...
