<font face="Times New Roman" size="+2">


Replace f(x) with y


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ x\ +\ 7]


Solve for x in terms of y


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ y\ -\ 7]


Swap the variables


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ x\ -\ 7]


Replace y with *[tex \Large f^{-1}(x)]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f^{-1}(x)\ =\ x\ -\ 7]


Follow these steps to create any inverse function (provided the inverse exists)
