Let X = { 1,2,3,4}, Y = {a,b,c,d} and f={(1,a), (4,b), (2,c),(3,d),(2,d)}. Then f is

Is the function f : A rarr B one-one and onto? : A={1,2,3,4}, B={a,b,c,d}, f={(1,a),(2,b),(3,c),(4,d)}

If A={1, 2, 3}, B={a, b, c, d}, f={(1, a), (2, b), (3, d)} , then f is

Let f={(1,a),(2,c),(4,d),(3,b)} and g^(-1) = {(2,a),(4,b),(1,c),(3,d)} then show that (gof)^(-1) = f^(-1) og^(-1) .

Let f={(1,a),(2,b),(3,c),(4,d)} and g={(a,x),(b,x),(c,y),(d,x)} Determine gof and fog if possible. Test whether fog=gof.

Let A={a,b,c,d} and f :A->A be given by f={(a,b),(b,d),(c,a),(d,c)} , write f^(-1)

Find the odd man out: Let X - {1,2,3,4), Y = {a,b,c,d,e)

Which of the following functions from AtoB are one-one and onto? f_1={(1,3),(2,5),(3,7)};A={1,2,3},B={3,5,7} f_2={(2, a),(3, b),(4, c)};A={2,3,4},B={a , b , c} f_3={(a , x),(b , x),(c , z),(d , z)}; A={a , b , c , d},B={x , y , z}
