The function given in the image is:

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

To find \( f(4) \), substitute \( x = 4 \) into the function:

\[
f(4) = -2(4) + 4
\]

\[
f(4) = -8 + 4 = -4
\]

So, \( f(4) = -4 \).

Would you like any further explanation on this? Here are a few related questions:

1. How do you find the value of a function for a given input?
2. What is the slope of the function \( f(x) = -2x + 4 \)?
3. How would the graph of \( f(x) = -2x + 4 \) look like?
4. What would \( f(x) = -2x + 4 \) become if you change the slope to 3?
5. How do you determine the x-intercept of the function \( f(x) = -2x + 4 \)?

**Tip:** When evaluating a function at a specific value, carefully substitute the value into the function and simplify step by step.
