(1) The document is a presentation for a Remedial Mathematics course titled "Every function is relation but all relation are not function". (2) It was prepared by Faglul Karim Raihan for their Business Administration department at Leading University in Sylhet, Bangladesh. (3) The presentation explains that every function creates a one-way relation between inputs and outputs, but relations can connect elements in both directions, so not all relations are functions.

- 3. What is relation? A "relation" is just a relationship between sets of information.
- 4. What is function? A function species a rule by which an input is converted to a unique output.
- 5. Every function is a relation but all relation are not function • Every function is one type of relation because every function creates by making an one way relation. But relation makes from both side for that reason all relation are not function.
- 6. Description by Drawing a b Drawing (a) is a function as it makes one way relation but drawing (b) makes relation from both side that’s why it only a relation.
- 7. Function and Relation in Vertical line a This graph shows a function, because vertical line cross this graph in one point and it also shows a relation.
- 8. b b These graph shows a relation, because vertical lines cross these graph more than one point and It's not a function.
