When
\( x = -4 \) for \( f(x) = (x)/(x^2 + 3x + 2) \), the function evaluates to
\((-2)/(3)\). Thus,
\( f(-4) = (-2)/(3) \).

To find the value of
\( f(x) \)when
\( x = -4 \) for the given function
\( f(x) = (x)/(x^2 + 3x + 2) \), substitute
\( x = -4 \)into the expression:


\[ f(-4) = (-4)/((-4)^2 + 3(-4) + 2) \]

Firstly, evaluate the expression in the denominator:


\[ (-4)^2 + 3(-4) + 2 = 16 - 12 + 2 = 6 \]

Now, substitute this value back into the original expression:


\[ f(-4) = (-4)/(6) \]

To simplify further, we can divide both the numerator and the denominator by their greatest common divisor, which is 2:


\[ f(-4) = (-2)/(3) \]

So, when
\( x = -4 \), the function
\( f(x) \) evaluates to
\( (-2)/(3) \). Therefore, the answer to the question is that the value of
\( f(x) \) when
\( x = -4 \) for the given function is
\( (-2)/(3) \).

This process demonstrates how to use the provided function to compute specific values, in this case, when
\( x = -4 \).

The probable question maybe:

What is the value of
\( f(x) \) when \( x = -4 \) for the function \( f(x) = (x)/(x^2 + 3x + 2) \)?
