Let `g={(1,2),(2,5),(3,8),(4,10),(5,12),(6,12)}`.
Is g a function? If yes, find its domain and range. If no, give reason.

If R = {(3,9),(3,12),(4,8),(4,12),(5,10),(6,12)} be a given relation, then domain of R =

Let f= {(1, 5), (2, 6), (3, 4)} g = {(4, 7), (5,8), (6,9)}. Then gof is :

If R = {(3, 9),(3, 12),(4, 8),(4, 12),(5, 10),(6, 12)} be a given relation, then range of R =

If the function f and g are given by f={(1,2),(3,5),(4,1)} and g={(2,3),(5,1),(1,3)} find range of f and g. Also write down fog and gofas set of ordered pairs.

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.

Let A={2,4,6}, B={8,10,12,14} and f={(2,8),(4,10),(6,12)} be a function from A to B . Show that f is one to one but not onto function.

Consider f:{3,4,5,6}to{8,10,12,13,14} and f={(3,8),(4,10),(5,12),(6,14)} . State whether f has inverse? Give reason.

Let f= {(2,4), (5,6), (8, -1), (10, -3) and g{(2, 5) (7, 1), (8, 4), (10, 13), (11,5)} be two real functions. Then, match the following. The domain of f-g, f+ g, f.g, (f)/(g) is domain of f nn domain of g. Then, find their images.
