I did not understand this step (y= 0>>ln x= 1>> x=e ) after we applied the quotient rule where is the 1 ans x^2? could you provide all the steps to the final result and the graph

Example 73. Graph the function y = Inc I Domain: r > 0 - Inc (quotient rule) 1 - In x = y = 0 -Inr = 1- > =e y(e) = - = 0.367 1 - = - (1 - Inx)2r (quotient rule) = -x - 2x + 2x In x = -3+2Inc y" = 0 - Inc= 101 00 -1 = 4.48
