The volume of a stock, or number of shares traded, is modeled during a given day by S(x) = x5 − 4x4 + 13x2 − 8x + 40. The cost per share of the stock during that day is modeled by C(x) = 0.005x4 − 0.05x2 + 0.2x + 3. Find a function for the total value of the stock traded on a given day. Enter a polynomial function V(x) to model the value during that day of the trades made of shares of that stock. V(x) = ()
