Functions are our way of expressing a relation between two sets, which is of fundamental importance to all of math. In fact, one could argue that there would be no math, only numbers, if there weren't any relations between the numbers.
How much is between two numbers.
The distance between two or more numbers
The relation, between two sets of objects, is a mapping which associates elements of the first set to those of the second set.
Common Difference means the difference between two numbers.

There are no differences in the numbers.
the distance between two or more numbers
In math, an interval is a set of real numbers with the property that any number that lies between two numbers in the set is also included in the set.
Common Difference means the difference between two numbers.
the quantitative relation between two amounts showing the number of times one value contains or is contained within the other
the quantitative relation between two amounts showing the number of times one value contains or is contained within the other:
Yes.
Yes, you can consider it a relation between the points on the x-axis, and the points on the y-axis. In fact, ANY subset of R squared (in other words, any subset of the points on a plane), including the empty set, sets that contain single points, and larger sets, can be considered a relation in R squared (i.e., two sets of real numbers).
