In each of the following cases, state whether the function is bijective or not. Justify your answer.
(i) \(f: \mathbb{R} \rightarrow \mathbb{R}\) defined by \(f(x) = 2x + 1\)
The above function is
(ii) \(f: \mathbb{R} \rightarrow \mathbb{R}\) defined by \(f(x) = 3 - 4x^2\)
Therefore, the above function is
Answer variants:
It is neither one-to-one nor onto
It is not bijective function since it is not one-to-one.
a bijective function
not a bijective function
It is not bijective function since it is not onto.
It is both one- to-one and onto
