The second derivative test of extrema states:

Let "f(x)" be a function with "f\\prime (x_0)=0". Then if "f\\prime\\prime(x_0)>0", the function has a local minimum at "x=x_0". If "f\\prime\\prime(x_0)<0", the function has a local maximum at "x=x_0" . If "f\\prime\\prime(x_0)=0", the second derivative test fails.

The function "h(x)" satisfies the conditions of the second derivative test at point "x_0=2" and "h\\prime\\prime(2)<0", hence the function "h" has a local maximum at "x=2".


Answer. D: relative(local) maximum
