2. Find the derivative for the following functions (complete solutions should be included in your logbook, completed prior to the beginning of class). This is preparatory work for discussions we will have next week regarding propagation of uncertainty: dy if y=x+7x-5x+4 dx dy if y = (x + 1)(2x-3) dx dy dx if y = (x + 1) (x - 1) dy if y = dx ** x+1 x-1 dx (2x2 if y = - dy x+7 (x-1)(x - 2x) if y = dx
