Let `A={1, 2, 3, 4} and B={4, 8, 9, 10}`. A function `f:A to B` given by `f={(1, 4), (2, 8),(3, 9), (4, 10)}` is a

Let A={1, 2, 3, 4} and B={-1 ,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12} . Let R={(1, 2), (2, 6), (3, 10), (4, 9)}subsetAtimesB be a relation. Show that R is a function and find its domain, co-domain and the range of R.

Consider the set A={1,2,3,4,5} , and B={1,4,9,16,25} and a function f:AtoB defined by f(1)=1 , f(2)=4 , f(3)=9 , f(4)=16 and f(5)=25 . Does f^-1 exists? Explain.

If A={1, 2, 3, 4, 5, 6} B={2, 4, 5, 6, 8, 9, 10}, "find" ADeltaB .

If A={1,2,3,4,5,6) and B={2,4,5,6,8,9,10} then A DeltaB is equal to

If A = {1, 2, 3,9, 4, 5}, B = {1, 4, 5,8,9,6} then find n ( A ∪ B ) .

Let A={1,2,3,4,5}, B={1,2,3,4) and f:A rarr B is a function, the

Let A={1,2,3,4,5}, B={1,2,3,4} and f:A rarr B is a function, then

Let A={1,2,3,4,5}, B={1,2,3,4} and f:A rarr B is a function, then
