1. [2+1+1+1=5 points] For some constants a, b and c, do the following: (a) Use the quotient rule to differentiate the function f(x) = (b) Rewrite the function in part (a) as f(x) using the product rule. = a 1 C (c) Rewrite the function in part (a) as f(x) = x the power rule. C b 3 x-3 (ax - b) and differentiate by b -2 - -X and differentiate using C (d) Show that the answers to parts (a), (b) and (c) are all the same.
