**Finding Maximum and Minimum Values of a Function Subject to a Constraint**

Find the minimum and maximum values of the function \( f(x, y, z) = 3x + 2y + 4z \) subject to the constraint \( x^2 + 2y^2 + 6z^2 = 4 \).

\[
f_{\text{max}} = \ \boxed{\rule{12em}{0.5pt}}
\]

\[
f_{\text{min}} = \ \boxed{\rule{12em}{0.5pt}}
\]
