Let $\mathrm{f}(\mathrm{x})=2^{\mathrm{x}}-\mathrm{x}^{2}, \mathrm{x} \in \mathrm{R}$. If $\mathrm{m}$ and $\mathrm{n}$ are respectively the number of points at which the curves $y=f(x)$ and $y=f^{\prime}(x)$ intersects the $x$-axis, then the value of $m+n$ is
Show Answer
Answer (5)
Solution
$\therefore \mathrm{n}=2$
$\Rightarrow \mathrm{m}+\mathrm{n}=5$
