Question

What is the value and is it minimum or max

Answer 1

Answer:

minimum and value of 4

Step-by-step explanation:

$\frac{dx}{dy} = 2x-8$

When $\frac{dx}{dy}=0$  we will be able to get the critical points.

$2x-8 =0$$x=4$

The graph is a quadratic graph with a 'U' shape, thus it has a minimum critical point.

Answer 2

Minimum and value is 4 !! I got it correct on a test!
