what is the inverse of ln Y ln x To find an inverse function we swap x and y and solve for y again x ln y ex eln y y ex Hence y 1 ex Answer link y 1 e x y ln x To find an inverse function we swap x and y and solve for y again x ln y e x e ln y y e x Hence y 1 e x
Let s look at how to find the Inverse of a log function Steps to get the inverse of a log function f x l o g b x are as follows 1 Change f x to y f x y 2 Swap x y x y y x 3 The inverse is found algebraically by switching the x and y values y ln x 1 x ln

1 Answer The answer is y lnx We find the answer the same way we find any inverse we swap x and y then solve ln and e functions cancel each other because they are inverses The answer is y ln x We find the answer the same way we find any inverse we swap x and y then solve y e x x e y swap ln x ln e y take logarithm of both sides ln x 1 Answer If y ln x2 then It is not a function as given a value for y there can be sometimes 2 values of x due to the plus minus sign If y ln x 2 then e y x 2 x sqrt e y It is not a function as given a value for y there can be sometimes 2 values of x due to the plus minus sign
Making our final answer y ex 2 Answer link y e x 2 The easiest way to find the inverse of a function is to swap x and y and solve for y y ln x 2 x ln y 2 We then raise e to the power of both sides to remove the natural logarithm x ln y 2 e x y 2 And subtract 2 to isolate y e x y 2 e x 2 y Making our final Hence 2 lnx ey or lnx ey 2 and x eey 2 Hence inverse function of f x ln 2 lnx is f x eex 2 Answer link x e e y 2 Calling y log e 2 log e x we have also e y 2 log e x and log e x e 2 e y then xe 2 e e y and finally x e e y 2 So with this procedure we obtained a function g such that x
