A moving company’s moving rates can be represented by the function f(x) = 3x 400, where x is the number of miles for the move. another moving company’s rates can be represented by the function g(x) = 5x 200. which function represents the difference between the moving companies' rates, h(x) = f(x) – g(x)? h(x) = 2x 200 h(x) = –2x 200 h(x) = 5x – 200 h(x) = 5x 600
