Derivative of an inverse function The function Vx+2+1 is one-to-one, for x = 0, and has an inverse on that interval. Find the slope of the curve y = f(x) at the point (3, 1). f(x) -V++1 y=xy-1-x-10 (1.3) (3, 1) y = f(x) 6 game! metb m = lane =1 y=fix) THEOREM 3.21 Derivative of the Inverse Let f be differentiable and have an inverse bish () %0 then f' is differentia
