# Let S = {a, b, c} and T = {1, 2, 3}. Find F–1 of the following functions F from S to T, if it exists.F = {(a, 3), (b, 2), (c, 1)}

(i) It is given that S = {a, b, c} and T = {1, 2, 3}

F : S T is defined as:

F = {(a, 3), (b, 2), (c, 1)}

= > F(a) = 3, F(b) = 2, F(c) = 1

Therefore, F-1: T S is given by:

F-1 = {(3, a), (2, b), (1, c)}.
