माना कि `f : {2, 3, 4, 5} rarr {3, 4, 5, 9}` तथा `g : {3, 4, 5, 9} rarr {7, 11, 15}` फलन है जो इस प्रकार परिभाषित है, f(2) = 3, f(3) = 4, f(4) = f(5) = 5 तथा g(3) = g(4) = 7 तथा g(5) = g(9) = 11 निकालें।

Explanation

gof (2) = 7, gof (3) = 7, gof (4) = 11, gof (5) = 11 अर्थात gof = {(2, 7), (3, 7), (4, 11), (5, 11)}
