The image provides a function \( f(x) = 4x - 7 \) and asks to find the value of \( f(4) \).

### Step-by-step solution:

1. The formula for the function is:
   \[
   f(x) = 4x - 7
   \]
   
2. To find \( f(4) \), substitute \( x = 4 \) into the formula:
   \[
   f(4) = 4(4) - 7
   \]

3. First, calculate \( 4 \times 4 = 16 \), so:
   \[
   f(4) = 16 - 7 = 9
   \]

Thus, \( f(4) = 9 \).

4. What would \( f(10) \) be using the same formula?
5. Can you explain how the function changes as \( x \) increases?

**Tip:** Always substitute the given value of \( x \) carefully to avoid small calculation errors.

Based on the function f(x) = 4x - 7, find the value of f(4).
