Function (Function) A function is a relation which the Member pages of the top pairs are matched with a couple of members only.Definition of a function is a relation r which provided that if (x, y) and (x, y) z and y = z. If f is a relation from A to B is called a function from A to f as a B, f. There are two properties: = A (meaning all of A member's membership is settled). Each Member in A match with only one member in the B. Example 1: set to A = {0, 2, 4, 8} and B = {1, 3, 5, 7} you shall verify that the.The following relation is a function from A to B? 1. a = {(0, 1), (2, 3), (4, 5), (8, 7)} 2. a = {(0, 1), (2, 3), (4, 5))} 3. = {(0, 1), (2, 3), (2.5), (4, 5), (8, 7)} How to make a function from A to B, since. = {0, 2, 4, 8} = A and A member of each pair with only one B members. It is not a function from A to B, since. ={0,2,4 } A Not as a function from A to B, since A 2. And 2 match twice is (2, 3) and (4, 5).
