WebIn general, if a function's graph does not pass the Horizontal Line Test, then the graphed function's inverse will not itself be a function; if the list of points contains two or more points having the same y -coordinate, then the listing of points for the inverse will have two or more points having the same x -value and thus will not be a … WebSep 7, 2024 · Use the inverse function theorem to find the derivative of g(x) = x + 2 x. Compare the resulting derivative to that obtained by differentiating the function directly. Solution The inverse of g(x) = x + 2 x is f(x) = 2 x − 1. We will use Equation 3.7.2 and begin by finding f′ (x). Thus, f′ (x) = − 2 (x − 1)2 and
