Round your answers to two digits. The following expression implicitly denes a function 1: : 11(u). 111L205 121:4 = 23 Part1 Find the derivative of o with respect to u at (114}, on} = {1, 1]: Part2 Find the linear {rstorder} approximation for 1: around on = 1. Express the approximation as 1(a) m an l b The coefficient a then is equal to|:|. The coefficient [1 then is equal to|:|. Part3 Find the elasticity of 1: around u\" = 1. as\") ZS
