关于形如y=mx+n+p(cx+d)(1/2)姨的函数值域的求解,其通用的方法是换元法,本文从两边平方法的角度对这个问题做一讨论,发现该方法在某些场合下比换元法更为简洁.
The general method for solving the range of functions of the form y = mx + n + p (cx + d) (1/2) is a metamorphic method. This article discusses this problem from the perspective of the two-sided method It is found that this method is more concise than the metamorphosis method in some occasions.
