a. Using the given g (x, v) = In Nilc - 2y), solve the local linear approximation of g at {25,2}. Then, use it to estimate In (#2435 - 4.04). b. Using the same given g (X, y] = In (1.6? - 23'), now, we denote that z=g (x, v], where the x and v are given as x=s4 + 91v\" and Fsecisw). Thus, solve for Ir:j'irwhen s=0 and w=1
