WebSep 27, 2024 · Verify that f(x) = 5x − 1 and g(x) = x + 1 5 are inverse functions. Solution: The functions are inverses of each other if g(f(x)) = x and f(g(x)) = x . Since both g(f(x)) = x and f(g(x)) = x are true, the functions f(x) = 5x − 1 and g(x) = x + 1 5 are inverse functions of each other.
