Let \(f: \mathbb{R} \rightarrow \mathbb{R}\) be a twice differentiable function such that \(\frac{d^{2} f(x)}{d x^{2}}\) is positive for all \(x \in \mathbb{R},\) and suppose \(f(0)=1, f(1)=4.\) Find the value of \(f(2)?\)

Define \(f: \mathbb{R} \rightarrow \mathbb{R}\) by \[f(x)= \begin{cases}(1-\cos x) \sin \left(\frac{1}{x}\right), & x \neq 0 \\ 0, &a...
