Solution Steps

Step 1: Understand the operation

The problem asks for \((f - g)(x)\), which means we need to subtract the function \(g(x)\) from \(f(x)\).

Step 2: Write down the given functions

\[ f(x) = -2x^2 + 3x - 2 \] \[ g(x) = x - 4 \]

Step 3: Subtract \(g(x)\) from \(f(x)\)

\[ (f - g)(x) = f(x) - g(x) = (-2x^2 + 3x - 2) - (x - 4) \]

Step 4: Distribute the negative sign

\[ (f - g)(x) = -2x^2 + 3x - 2 - x + 4 \]

Step 5: Combine like terms

\[ (f - g)(x) = -2x^2 + (3x - x) + (-2 + 4) \] \[ (f - g)(x) = -2x^2 + 2x + 2 \]

The simplified form of \((f - g)(x)\) is \(-2x^2 + 2x + 2\).

Final Answer

\(\boxed{-2x^2 + 2x + 2}\)
