f(x)= 10 - 4x A function is shown.

To find the value of \( f(-4) \) for the function \( f(x) = 10 - 4x \), we substitute \(-4\) for \(x\):

\[ f(-4) = 10 - 4(-4) \]

Now, calculate the multiplication:

\[ f(-4) = 10 - 4 \times -4 = 10 - (-16) = 10 + 16 = 26 \]

Thus, the value of \( f(-4) \) is

\[ \boxed{26} \]
