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

To find the value of \( f(-4) \) for the function \( f(x) = 10 - 4x \), we need to substitute \( -4 \) for \( x \) in the function.

Let's calculate it:

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

So, yes, the value of \( f(-4) \) is indeed \( 26 \).

Given the function \( f(x) = -3 + 8x^2 \), you can find the value of \( f \) for any particular \( x \) by substituting that value into the function.

If you would like to evaluate \( f(x) \) for a specific value of \( x \), please provide that value. Alternatively, if you have any other questions related to the function, feel free to ask!
