When applying the quotient rule, it is often preferable to leave the answer in the form that the rule gives, rather than simplifying (unless, as will happen later in the course, there are further computations to be done with the derivative). Also, each problem below requires only a calculation using rules you know, so it suffices to show your work. No explanations are needed. (1) Use the rules for differentiation to find the derivative of x + 12 x15x + 2 - (2) From the information f(2)= 10, f'(2) = -4, g(2) = 3, and g'(2) = 5, compute the derivative of the ratio f(x)g(x) f(x) + g(x) at x = 2.
