WebIf you can find the inverse of a function then you can "undo" what the function did. For example, if you now the formula to convert degrees Celsius into degrees Fahrenheit, the inverse will convert Fahrenheit to Celsius. If a function does not have an inverse, it tells us something about the the function and it's shape. WebSep 3, 2015 · The test to verify if a function f is the inverse of another function g is given by using the composition of the functions such as this, f (g (x))= x. Therefore, to answer your question, f (g (x))=x is saying f is the inverse of g. f (g (x))=x is saying f is the inverse of g but g is not the inverse of f, g (f (x))≠x.
