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. WebIf a function does not give all of the input-output pairs for both functions, then it is possible that the functions may not be inverses of each other. In order for two functions to be inverses of each other, they must satisfy the following criteria: 1. Each input of one function corresponds to a unique output of the other function. 2.
