To find \((f - g)(x)\), we start by subtracting \(g(x)\) from \(f(x)\).
Given:
- \(f(x) = 6x - 2\)
- \(g(x) = 2x + 4\)
Now, we can express \((f - g)(x)\) as follows:
\[ (f - g)(x) = f(x) - g(x) = (6x - 2) - (2x + 4) \]
Distributing the negative sign:
\[ (f - g)(x) = 6x - 2 - 2x - 4 \]
Now, combine the like terms:
\[ (f - g)(x) = (6x - 2x) + (-2 - 4) = 4x - 6 \]
Thus, the final answer is:
\[ (f - g)(x) = 4x - 6 \]
