Use the Mean Value Theorem to prove that if f'(x)<0 for all x in(a,b) then f is decreasing in (a,b). Mean Value Theorem: If the function f is continuous in [a,b] and differentiable on (a,b), there exists at least one number c in (a,b) for which f'(c)=( f(b) - f (a) ) / (b - a) -- Sent from my iPhone -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 120.126.194.203
