Those functions are one-to-one on those intervals and have inverses. The graphs of a function and its inverse are symmetric in the line y = x. This Demonstration plots the graphs of ...

Webb10 nov. 2024 · You’re surely familiar with the idea of an inverse function: a function that undoes some other function. For example, f(x)=x3 and g(x)=3 p x ... As you can see, the recipe (for proving that a function is not surjective) is to locate some y-value in the co-domain, for which there is no x-value in the domain where f(x)=y.
