answer:

The answer to your question is letter D. 3x - 1

Step-by-step explanation:

Data

f(x) = 5x - 2

g(x) = 2x + 1

(f-g)(x) = ?

Process

1.- To solve this problem just subtract g(x) from f(x)

(f-g)(x) =  f(x) - g(x)

- Substitution

 (f-g)(x) = 5x - 2 - (2x + 1)

- Simplification

 (f - g)(x) = 5x - 2 - 2x - 1

 (f - g)(x) = (5x - 2x) + (-2 - 1)

- Result

(f - g)(x) = 3x - 3
