The function f(x) = 2x2 + 3 represents the rate of a boat traveling with the current in miles per hour. the function g(x) = x + 2 represents the time the boat traveled in hours. solve (f • g)(2), and interpret the answer. (f • g)(2) = 15, the distance in miles the boat traveled (f • g)(2) = 15, the number of boats (f • g)(2) = 44, the distance in miles the boat traveled (f • g)(2) = 44, the number of boats
