Question
How do I compute the function f(x+h)-f(x) when f(x) is as follows?
## Understanding Function Increments

### Given Function

The function is defined as \( f(x) = -3x + 5 \).

### Task

Compute the following expression:

\[ f(x + h) - f(x) = \]

### Explanation

To solve the expression \( f(x + h) - f(x) \), follow these steps:

1. **Substitute \( x + h \) into the function**:
   - Calculate \( f(x + h) \).

2. **Apply the function rule**:
   - Use the given expression of the function \( f(x) = -3x + 5 \).
  
3. **Subtraction**:
   - Subtract \( f(x) \) from \( f(x + h) \).

This process helps in understanding how changes in the input \( x \) (increment \( h \)) affect the output of the function.
