the total number of visitors who went to a theme park from october 1 to 10 can be modeled by the function f(x) = 126x3 + 279x2 + 90x + 450 and the number of shows played at the theme park from october 1 to 10 can be modeled by g(x) = 18x + 45, where x is the number of days since october 1. write an expression that correctly describes the average number of visitors per show? (hint: average is the total visitors divided by the number of shows.)
