Ex 1.3, 1 - Chapter 1 Class 12 Relation and Functions - NCERT Let f: {1, 3, 4} → {1, 2, 5} and g: {1, 2, 5} → {1, 3} be given by f = {(1, 2), (3, 5), (4, 1)} and g = {(1, 3), (2, 3), (5, 1)}. Write down gof. Let us draw figures to denote set f and set g We see that gof (1) = 3 gof (3) = 1 gof (4) = 3 So, gof = { (1, 3), (3, 1), (4, 3)}
