The difference betweeh the two companies' moving rates is:
(f - g)(x) = -2x + 200
Here we have two functions:
f(x) = 3x + 400
g(x) = 5x + 200
These functions represent the moving rates for two different companies.
If we want to find the difference between the moving rates, we just need to take the difference between the functions:
(f - g)(x) = f(x) - g(x) = (3x + 400) - (5x + 200) = -2x + 200
So the difference betweeh the two companies' moving rates is:
(f - g)(x) = -2x + 200
