Min/Minimum.

Explanation:

The coefficient of ${x}^{2}$ is a positive number ($+ 1$). Hence, the shape of your quadratic is a $U$ shape.

You can also use calculus to determine it. Just take the double derivative.
${d}^{2} / \left({\mathrm{dx}}^{2}\right) \left({x}^{2} + 6 x + 8\right) = 2$
You get $2$ for all values of $x$. The positive number suggests a minimum. A negative suggests a maximum.
