WebFinding inverse functions We can generalize what we did above to find f^ {-1} (y) f −1(y) for any y y. [Why did we use y here?] To find f^ {-1} (y) f −1(y), we can find the input of f f that corresponds to an output of y y. This is because if f^ {-1} (y)=x f −1(y) = x then by definition of inverses, f (x)=y f (x) = y. WebLearn how to find the formula of the inverse function of a given function. For example, find the inverse of f (x)=3x+2. Inverse functions, in the most general sense, are functions that "reverse" each other.
