Final answer:

The correct composition of the functions f(x) and g(x) is (f.g)(x) = x - 15.92, but this does not match any of the options given in the question, indicating a potential problem with the provided information.

Step-by-step explanation:

The composition of two functions f(x) and g(x) is found by applying g first and then f. Since g(x) = 3.02 - 7 simplifies to g(x) = -3.98, we can substitute this into f to get (f ∙ g)(x) = x + 4(-3.98). The composition (f.g)(x) therefore is (f.g)(x) = x - 15.92, which unfortunately does not match any of the provided options. It's possible that there might be an issue with the given functions or the options provided.
