在求反函数的问题中,经常有同学把f-1(x+1)误以为f(x+1)的反函数,其实,只要把好:f(x+1)→f(x)→f-1(x)→f-1(x+1)这一脉络,就可以捋顺二者关系.下面从三个
In the problem of finding the inverse function, students often mistook f-1 (x + 1) for the inverse function of f (x + 1). In fact, as long as f (x + 1) → f f-1 (x) → f-1 (x + 1) this context, you can go along with the relationship between the two from the following three
