Gary borrowed a total of $10,000. Part of the money was borrowed form a Credit Union that charged 5.5% simple interest. The remainder was borrowed from a friend to whom Gary paid 2.5% simple interest. Gary paid his friend back after 1 year and paid the Credit Union back after 2 years. If the total amount Gary paid in interest was $717.50, how much did Gary borrow from each source? Given f(x) = x^2 - 2x + 5 and g(x) = 2x + 3, find (f g)(x) and (g f)(x). Label clearly, Simplify.
