specific-question A recent question with a deprecated tag and no top-level tag: How can I proof the minimum of two quasiconcave functions is also quasiconcave? What would be suitable tags there - perhaps convex-analysis and ca.classical-analysis-and-odes?

I know that $f : R^n \xrightarrow{} R$ and $g : R^n \xrightarrow{} R$ are quasiconcave functions. How can I prove that the function $h(x)=\min\left\{f(x),g(x)\right\}$ is also quasiconcave?
I will point out that the (discrete-mathematics) tag is deprecated on MathOverflow, see the tag-info. But I will leave the choice of the tags for more experienced users. — Martin Sleziak 18 secs ago
