Answer:

minimum

Explanation:

The given function is

$y = - 4 + 3 {x}^(2)$

The coefficient of the quadratic term is what we use to determine whether the function is minimum or maximum.

The coefficient of the quadratic term is a=3.

Since 3>0, the function has a minimum turning point.

On the other hand if the coefficient is less than zero, the function will have a maximum turning point.

The quadratic term is the term with degree 2.
