Learn 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 takes a to b , then the inverse, , must take b to a . Or in other words, f ( a) = b ( b) = a .
Mar 23, 2016 · To attempt to find an inverse function, let y = f (x) and solve for x in terms of y ... y = x2 − 1. Add 1 to both sides to get: y + 1 = x2. Transpose and take square root of both sides, allowing for either sign: x = ± √y + 1. This does not determine a unique value for x in terms of y.
Learn how to find the inverse of a function, such as f(x) = x^2-1, and its graph. See examples, formulas, and rules for common functions and their inverses.
