Let A={a,b,c} and B={1,2,3} . Let f : A rarr B be a function where f= {(a,1),(b,2),(c,3)} Find f^-1 , if exists in each case.

If A={a,b,c},B={p,q,r} then find AxxB and B xx A .

If A={2,3,5,7,11,13} and B={1,2,5,7,11},then find Ann B

Let R be the relation defined in the set A={1,2,3,4,5,6,7,8,9} by R={(a,b,):" both a and b are either odd or even"} . Show that R is an equivalence relation. Further show that all the lements of the subset {1,3,5,7,9} are related to one another and all the lement of the subset {2,4,6,8} are related to one another but no element of the subset {1,3,5,7,9} is related to any element of the subset {2,4,6,8} .

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

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