Answer 1

Answer:

What is the Difference Between Relations and Functions?

Differentiating Parameter Relations Functions

Definition A relation is a relationship between sets of values. Or, it is a subset of the Cartesian product A function is a relation in which there is only one output for each input.

Denotation A relation is denoted by “R” A function is denoted by “F” or “f”.

Example R = {(2, x), (9, y), (2, z)}

** It is not a function, as “2” is input for both x and z.

F = {(2, x), (9, y), (5, x)}

Note: Every relation is not a function. Every function is a relation
