If `f(x) = sqrt2 x x in Q - {0} , 3x x in Q^(c)`, then define fof(x) and hence defined (fofof...of(x) where f is n times

If f(x)={(sqrt(2)x,xepsilonQ-{0}),(3x,xepsilonQ^(c)):} then define foff(x) and hence define fofof…………. f(x) where f is n times.

If f(x)={(sqrt(2)x,xepsilonQ-{0}),(3x,xepsilonQ^(c)):} then define foff(x) and hence define fofof…………. f(x) where f is n times.

If function f(x)=sqrt(2) when x in Q and 0 when x!in Q then (fof)sqrt(4)=

If f\ : R-: R be defined by f(x)=(3-x^3)^(1//3)\ , then find fof(x)

If f\ : R-> R be defined by f(x)=(3-x^3)^(1//3)\ , then find fof(x)

If f: R → R is defined by f (x) = (3 –x) then value of of fof(x)

If f:R-:R be defined by f(x)=(3-x^(3))^(1/3), then find fof(x)

If f(x) = x/(sqrt(1+x^2) then fofof(x)

If f(x) = x/(sqrt(1+x^2) then fofof(x)
