WebHow do you tell if a function is invertible from a graph? It is based on interchanging letters x & y when y is a function of x, i.e. y = f (x). Then solve for this (new) y, and label it f–1(x). If f (x) passes the HORIZONTAL LINE TEST (because f is either strictly increasing or strictly decreasing), then and only then it has an inverse. WebIf we can find the input x ( t) in terms of output y ( t) (by solving mathematically), does that always mean the system is invertible? Is there any possibility that can lead to the failure …
