Conclusion: The inverse of a function is not necessarily a function. So...when is the inverse of a function also a function? f-1(x), the inverse, is itself a function only when f(x), the original function, is a one-to-one function. Remember: 1 to 1 functions must pass the ...
ofaFUNCTIONf(x)=y》For a function y=f(x)to have an inverse function,f must be one-to-one.Then for each x in its domian there is exactly one y in its range;furthermore,to each y in the range,there corresponds exactly one x in the domain.The correspondence from the中学生数学:高中...
I get the x-stuff by itself on one side of the "equals" sign: xy = 5y − 2 Then I solve for x=: And then switch the x's and y's: So I've found the inverse, and it's another rational function; in particular, the inverse is indeed a function. The domain and range of ...
f is written as f –1: note that this does not mean ‘1 over f ’. The graph of y = f –1(x) is the reflection in y = x of the graph of y = f (x).例题：To find the inverse of a function x → y (i) interchange x and y(ii) find y in terms of x.小试牛刀：

Here we have the function f(x) = 2x+3, written as a flow diagram:The Inverse Function goes the other way:So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)...
