Question

Find the minimum or maximum of the function below.

Answer 1

Answer:

A) minimum of -2

Answer 2

Answer:

A. minimum at x = -2.

Step-by-step explanation:

Finding the derivative:

f'(x) = 12x.

12x = 0 for a maxim/ minimum.

x = 0.

As the second derivative (12) is positive,  we have a minimum value when x = 0.

So the function has a minimum value  where f(x) = 6(0)^2 -2 = -2.
