A profit formula for a single tire can be modeled by the function P(t) =-18+ 850t-725. Each set of tires can be modeled by the function f(s) = 4s. Which composite function can be used to determine the profit function in terms of the number of sets of tires?

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
