If `f: NrarrN`,and `x_2> x_1=> f(x_2)>f(x_1)` for `x_1,x_2 in N` a n d`f(f(n))=2nAAn in N ,` then `f(2)`=_________`

If f: N to N, and x_(2) gt x_(1) implies f(x_(2)) gt f(x) AA x_(1), x_(2) in N and f(f(n))=3n AA n in N," then " f(2)= _______.

f(x)=(x-2)^(2)x^(n),n in N then f(x) has

Let f : N rarr N be defined as f(x) = 2x for all x in N , then f is

Let f:N rarr N be defined by f(x)=x^(2)+x+1,x in N. Then is f is

f_(n)(x)=e^(f_(n-1)(x))" for all "n in N and f_(0)(x)=x," then "(d)/(dx){f_(n)(x)} is

Let f(x)=(x-1)(x-2)(x-3)...(x-n),n in N, and f(n)=5040 Then the value of n is
