माना कि A = {a, b, c, d}, B = {p, q, r, s}, C = {x, y, z} माना कि `f : A rarr B` तथा `g : B rarr C` इस प्रकार परिभाषित है `f(a) = p, f(b) = q, f(c) = r, f(d) = s` तथा `g(p) = x, g (q) = x, g(r) = y. g(s) = z`. `gof : A rarr C` निकालें।

Explanation

gof (a) = x, gof (b) = x, gof (c) = y, gof (d) = z अर्थात gof = {(a, x), (b, x), (c, y), (d, z)}
