Define a function as a set of ordered paris.

Let A={0, 1, 2, 3} and B={1, 2, 3, 5, 7, 9} be two sets. Let f: A to B be a function given by f(x)=2x+1 . Represents this function as a set of of ordered pairs

Let A={9, 10, 11, 12, 13, 14, 15, 16, 17} and let f:A to N be defined by f(n)= the highest prime factor of ninA . Write f as a set of ordered pairs and find the range of f.

let A = { 1,2,3,4} and B = { 2,5, 8, 11,14} be two sets. Let f : A to B be a function given by f(x) = 3x -1 . Represent this function (i) by arrow diagram (ii) in a table form (iii) as a set of ordered pairs (iv) in a graphical form

A relation R is defined on the set z of integers as follows : (x,y) in RR hArr x^(2) +y^(2) = 25 . Express R and R^(-1) as the set of ordered pairs and hence find their respective domains.
