Part 1: Identify the formulas: Part 2: Find the derivative

Part 1. Identify the following formulas: 1) For any real number k, if y = x* then a xk = kxk-1 dx 2) -C = 0. dx d 3) dx [f (x) + g(x]] = d dx f(x)+ dx 9 (x). 4) Let f (x) = f(x)g(x). Then f'(x) = f(x)g'(x) + g(x)f'(x). Part 2. Find the derivative with respect to x: 1) f (x) = Vx+5 2) a(x) = 2x2 + 5x + 3
