函数是中学数学中极其重要的内容之一.它是数形结合的重要体现之一,它与一元一次不等式、一元一次方程、一元二次方程方程、一元二次不等式有着密切的联系,在学生的数学学习过程中有着重要的意义和作用.函数在中学数学中最具复杂性,学生对函数的学习往往不是一帆风顺的,因此通过多年的教学总结出对函数学习的一点看法,与大家共享. Function is one of the most important contents in the middle school mathematics.It is one of the most important manifestation of the combination of number and form.It is closely connected with the one-time inequality, the one-degree-one-degree equation, the one-degree quadratic equation and the one-dollar two inequality, The function of mathematics is the most complicated in middle school, and the students’ learning of the function is not always easy. Therefore, through years of teaching, we can sum up the point of view of function learning and share with you.
