Let f(x) represent the number of Euros you can buy with x dollars, and let g(x) represent the number of yen you can buy with x Euros.

(a) Find a function that relates dollars to Euros.

(b) Find a function that relates Euros to yen.

(c) Use the results of parts (a) and (b) to find a function that relates dollars to yen. That is, find (g ° f)(x) = g(f (x)).
