Brody Casey · Answer 1

g (f (x)) = 3.15x

Step-by-step explanation:

To find the number of Japanese yen equivalent to x russian rubles, we need to put one function into another.

If we take f (x) and put in into g (x), we will get Japanese yen in terms of rubles. Thus,

g (f (x)) = 90 (0.035x)

g (f (x)) = 3.15x

THis is the composite function which represents the number of Japanese yen equivalent to x Russian Rubles.
