Let f be the function defined by f(x)=xsinx with domain [0,inf). The function f has no absolute minimum and no absolute maximum on its domain. Why does this not contradict the extreme value theorem? A. The domain of f is not an open interval

B. The domain of f is not a closed and bounded interval

C. The function f is not continuous on its domain

D. The function f is not differentiable on its domain
