F={2,3,5}

Statewith reasons whether the following functions have inverse f:{2,3,4,5} to {5,10,17,26} with f={(2,5)(3,10),(4,17),(5,26)}

If f={(2,5),(3,1),(5,2),(8,5),(10,2),(11,5)} is a function,write its range.

If the mappings f and g are given by : f={(1,2),(3,5),(4,1)} and g={(2,3),(5,1),(1,3)} , write fog.

If the mappings f and g are given be f = {(1,2),(3,5),(4,1)} and g = {(2,3),(5,1),(1,3)} , write fog .

If the mappings f and g are given by f={(1,2),(3,5),(4,1) and g={(2,3),(5,1),(1,3)}, then write fog.

Fill in the blank: Let f = (1,2), (3,5), (4,1) and g = (2,3), (5,1), (1,3) then gof = _______and fog = _________.

Let f:{1,2,3}rarr{3,5,7} and g:{3,5,7}rarr{7,23,47} given by f(1)=3,f(2)=5,f(3)=,g(3)=7,g(5)=23,g(7)=47 (i).Find gof
