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

The domain of R = {1, 2, 3, 4} = A, The co-domain is B, Range of R is given by {3, 6, 10, 9}.
