What is the difference between function and a relation?

Answer 1

Good question. A relation is simply that; any x-value to create any y-value. A function, however, cannot be defined for multiple values of x. In other words, for a relation to be a function, it must have singular values for all x within its domain.

Answer 2

A function is a specific type of relation.

Both a function and a relation have input and output. A function is limited to only one output for each input, though. A relation has no limit on how many outputs each input can have.
