Which of the following functions is injective ?

Which one of the following functions f:RtoR is injective?

Prove that the function f:A rarr B is one-one onto,then the inverse function f^(-1):B rarr A is unique.

Using the definition, Prove that the function f:A to B is invertible if and only if f is both one-one and onto.

Prove that the function f:N rarr N, defined by f(x)=x^(2)+x+1 is one-one but not onto
