To find \((f + g)(x)\), we need to add the functions \(f(x)\) and \(g(x)\):
Given:
- \(f(x) = 6x - 2\)
- \(g(x) = 2x + 4\)
Now, we add these two functions together:
\[ (f + g)(x) = f(x) + g(x) = (6x - 2) + (2x + 4) \]
Combining like terms:
- Combine the \(x\) terms: \(6x + 2x = 8x\)
- Combine the constant terms: \(-2 + 4 = 2\)
Putting it all together, we get:
\[ (f + g)(x) = 8x + 2 \]
Thus, the final answer is:
\[ \boxed{8x + 2} \]
