Show that `f:R_(+) rarr R_(+)` defined by `f(x)=(1)/(2x)` is bijective, where `R_(+)` is the set of all non-zero positive real numbers.

Show that the function f:R_(0)rarr R_(0), defined as f(x)=(1)/(x), is one-one onto,where R_(0) is the set of all non-zero real numbers.Is the result true,if the domain R_(0) is replaced by N with co-domain being same as R_(0)?
