Mathematics - Application of Derivative Question with Solution | TestHub

$f(x)=\{\begin{array}{cllcc}\left(\sqrt{2}+\sin \frac{1}{x}\right)e^{\frac{-1}{|x|}}& \text{ if }& x\ne 00& \text{ if }& x=0\end{array}$ Number of points where $f(x)$ has local extrema when $x\ne 0$ be $n_1.n_2$ be the value of global minimum of $f(x)$ then $n_1+n_2=$
