1Cademy - An inventory tracking system calculates daily storage fees using the function $f(x) = 5x - 1$, where $x$ represents the number of units stored. A reverse function, $g(x) = \frac{x+1}{5}$, is used to determine the number of units based on the daily fee. During an annual system audit, a database administrator must algebraically verify that these two functions are exact inverses. The administrator will recall that this verification is mathematically complete only when the compositions $g(f(x))$ and
