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. For example, if f f takes a a to b b, then the inverse, f^ {-1} f −1, must take b b to a a. Or in other words, f (a)=b \iff f^ {-1} (b)=a ...
