1.	Let the funciton `f:R to R` be defined by `f(x)=2x+sin x`. Then, f isA. one-to-one and intoB. one-to-one but not ontoC. onto but not one-to-oneD. neither one-to-one nor onto
Answer» Correct Answer - A Clearly, g(x)=2x is one-one and onto and it is a strictly increasing functions. Therefore, f(x)=2x+sin x both one-one and onto.
