is a function that "reverses" another function: if the function f applied to an input x gives a result of "y", then applying its inverse function g to y gives the result "x", and vice versa.
To solve this type of functions you need t follow some steps.
The first one consist in change the "x" for "y", for example, if you have this function F(x)=x+6 you change the first "x" like this y=x+6. The next step that you need is do the same but know with all the letters in the function and is something like this X=y+6. The last thing is let alone the "y" Y=x-6.
And those are the steps that you need to solve this type of functions.
