the rate of change of f(x) is least at x=?答案说f'(x) is least at the point of inflection point of the curve这个怎么理解?答案把rate of change默认为了instantaneous rate of change所以才直接说f'(x)?还有拐点不是和二阶导数

the rate of change of f(x) is least at x=?
答案说f'(x) is least at the point of inflection point of the curve这个怎么理解?答案把rate of change默认为了instantaneous rate of change所以才直接说f'(x)?还有拐点不是和二阶导数有关吗?和一阶导数有什么关系?

答案和解析
x点为导数值最低的点,f(x)的二阶导数在x点为0,如果x点存在二阶导数
