有的题目中隐含着一些条件,这些含蓄不露的条件,解题时若能准确巧妙地挖掘出来,便可以发散思维,探索、创新,稳操胜券.一、从概念的准确性、严谨性入手挖隐含例1反比例函数的表达式为y=(m-1)xm2-2,则m的值为.解:依题意有m-1≠0,m2-2=-1,解得m=-1.点评:本题将m隐含在反比例函数的 Some topics imply conditions, these hidden conditions, if you can accurately dig out when solving problems, you can diverge thinking, exploration, innovation, stability and success. First, the concept of accuracy and rigor The expression of the inverted inverse function of the hidden example 1 is y=(m-1)xm2-2, and the value of m is: Solution: There is m-1≠0, m2-2=-1 according to the problem meaning, and the solution m = -1. Comments: This question will be implicit in the inverse function of m
