Relation is the subset of Cartesian product ( A*B). Function is the subset of relation which have a unique image of every element in its domain to its co domain . No every relation is not a function as function should have unique image.

Relation is all possible pairs formed by two set while functions are the specific pairs. Relate function as a Machine. In Machine(eg. R.O water filter) you put input(water) and you get output (pure water) but you cannot put stones in machine, machine will not accept it. Similarly function is the machine where you cannot put all values for that specific function and as output you get a value. So Every relation is not function
