If A={1,2,3},f={(1,1),(2,2),(3,3)} then on A, f is

If f={(1,2),(2,-3),(3,-1)} then find (i)2+f (ii) f^(2) .

If f={(1,2),(2,-3),(3,-1)} then find (i)2+f (ii) f^(2)

If X = { 1 , 2 , 3} and Y = {0 , 1} and f : X to Y defined by f = { (1 , 1) , (2 , 1) , (3, 0) } , then f is

If f= {(1, 2), (2, -3), (3, -1)} then find: (i) 2f, (ii) 2+f , (iii) f^(2) , (iv) sqrt(f)
