在文[1]、[2]中,两位老师已经对函数y=ax+(b/x)(ab≠0)的图像、性质进行了系统的研究,读后我很受启发.函数y=ax+(b/x)(a、b∈R_+)的图像与二次函数的图像有许多相似之处,在教学实践中,我将此函数的性质与二次函数的性质进行类比研究,通过四个思维环节:㈠特征问题图像化㈡单调问题特征化㈢最值问题单调化㈣不等 In [1] and [2], two teachers have systematically studied the properties of the image y = ax + (b / x) (ab ≠ 0) There are many similarities between the image of ax + (b / x) (a, b∈R_ +) and the quadratic function image. In teaching practice, I compare the property of this function with that of quadratic function, Four aspects of thinking: (i) Imageization of characteristic issues (ii) Characterization of monotony problems (iii) Monotonicity of the most valuable issues (iv)
