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
