Question

Is y=-4+3x^2 minimum or maximum

Answer 1

Answer:

minimum

Step-by-step 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.
