To evaluate the expression \( 4f^2 + g \) for \( f = -3 \) and \( g = 6 \), we first calculate \( f^2 \):
\[
f^2 = (-3)^2 = 9
\]
Next, we multiply this result by 4:
\[
4f^2 = 4 \times 9 = 36
\]
Then, we add \( g \) to this result:
\[
4f^2 + g = 36 + 6 = 42
\]
Therefore, the value of the expression \( 4f^2 + g \) is \( \boxed{42} \).
