If \(\mathbb{R}\) be the set of real numbers, which of the following is one-one? |
\(f:\mathbb{R}\rightarrow \mathbb{R}, f(x)=\sin x\) \(g:\mathbb{R}\rightarrow \mathbb{R}, g(x)=\cos x\) \(h:\mathbb{R}\rightarrow \mathbb{R}, h(x)=e^{x}\) None of these |
\(h:\mathbb{R}\rightarrow \mathbb{R}, h(x)=e^{x}\) |
Exponential is one-one. |
