WebAnswer (1 of 2): Graph the function, and see if it passes the “Horizontal Line Test”. If there exist any horizontal lines that intersect the function more than once, then it will not have an inverse. On the other hand, if no such line exists, then the function will have an inverse. WebA General Note: Inverse Function. For any one-to-one function f(x) = y, a function f − 1(x) is an inverse function of f if f − 1(y) = x. This can also be written as f − 1(f(x)) = x for all x in the domain of f. It also follows that f(f − 1(x)) = x for all x …
