Question

what is relation and functions ?

Good evening friends.​

Answer 1

Step-by-step explanation:

Relations and functions – these are the two different words having different meanings mathematically. ... The relation shows the relationship between INPUT and OUTPUT. Whereas, a function is a relation which derives one OUTPUT for each given INPUT. Note: All functions are relations, but not all relations are functions.

A relation is a set of inputs and outputs, and a function is a relation with one output for each input.

For example, y = x + 3 and y = x2 – 1 are functions because every x-value produces a different y-value. A relation is any set of ordered-pair numbers. In other words, we can define a relation as a bunch of ordered pairs.
