由于函数的单调性、极值、最值都与其导函数有着紧密的联系,而函数图像既是表述函数问题的重要工具,又是函数性质的直观反映,因此近几年的高考中出现了不少有关导数与函数图像的交汇题.这种问题在高考中常常以创新题的面貌出现,多以选择题、填空题的 Because the monotonicity, extreme value, and the maximum value of a function are closely related to its derivative function, function images are both an important tool for expressing function problems and an intuitive reflection of the nature of functions. Therefore, many of the college entrance examinations have appeared in recent years. The intersection of derivatives and function images. This problem often appears in the face of innovative questions in the college entrance examination, and more choice questions, fill in the blank questions
