A real-valued function f on an interval (or, more generally, a convex set in vector space) is said to be concave if, for any x and y in the interval and for any t in [0,1],
A function is called strictly concave if
for any t in (0,1) and x ≠ y.
For a function f:R→R, this definition merely states that for every z between x and y, the point (z, f(z) ) on the graph of f is above the straight line joining the points (x, f(x) ) and (y, f(y) ).
A function f(x) is quasiconcave if the upper contour sets of the function are convex sets.

probably not? the roof of the cave or tunnel might collapse and you will be buried alive. or some huge debris will fall on your head. but then again, anything is possible. and depends on how close the cave or tunnel is to the bomb.
