$$f$$ is a finite function whose domain is the letters a to e. The following table lists the output for each input in $${f}^{\prime}$$ domain.Is $${f}$$ invertible? ![](http://admin.getprephub.com/media/editor/problem%2018_20220823193457767711.png) ![](http://admin.getprephub.com/media/editor/Screenshot%202022-09-23%20190623_20220923133634199146.png)

Given that; $$f(a)=5, f(b)=4, f(c)=3, f(d)=2, f(e)=1$$ All the elements of the domain have unigue image. Therefore, $$f$$ is invertible. ![](http://admin.getprephub.com/media/editor/Screenshot%202022-09-23%20190947_20220923133957350623.png)
