函数是中学数学最基本的内容,函数的数学思想贯穿整个高中数学学习的始终,定义域是函数“三要素”(定义域、值域、对应法则)之一,是函数最本质的特征.在解决问题的过程中,如果忽视函数的定义域,常常会事倍功半,甚至误入歧途,在求函数解析式时,必须考虑函
Function is the most basic content of high school mathematics. Mathematical thinking of the function runs through the entire high school mathematics learning. The definition domain is one of the three elements of function (domain, range, and corresponding law), and is the most essential feature of the function In the process of solving problems, if you ignore the domain of the function, it will often do more with less, or even go astray. When seeking the function analytic formula, you must consider the letter
