Answer:
Step-by-step explanation:
f(x)= x^2 - 6x + 8
a of s= 6/2 = 3
(3)^2 - 6(3) + 8
9 - 18 + 8
-9 + 8 = -1
(3, -1)
answer is B
1= -6
2= -5
3= -4
4= -3
5= 0
6= 3
Given

To obtain the minimum value of y, we first take the derivative of y
The derivative of y is:

Equating

gives the minimum value we require.
Doing that, we have:

So that

Therefore, the minimum value is x = 3
