Let f:N rarr N, where f(x)=x+(-1)^(x-1), then the inverse of is.

f:N to N, where f(x)=x-(-1)^(x) , Then f is

f:N to N, where f(x)=x-(-1)^(x) , Then f is

Let f:N rarr N given by f(x)=x+(-1)^(x+1), then

Let f: N rarr N be defined by f(x)=x^(2)+x+1 then f is

If f:N rarr N is defined by f(x)=2x+5 then f is

The function f:N rarr N defined by f(x)=x-5[(x)/(5)] where N is a set of natural numbers,then

If f(x)=(a-x^n)^(1/n) then find f(f(x))

Prove that f:N rarr N defined by f(x)=2x,x in N is one-one and into.

Show that f:N rarr N given by f(x)={{:(x+1", if x is odd"),(x-1", if x is even"):} is both one-one and onto.
