Its been awhile since I have done compleating the square, can you please help me?
Determine whether the given quadratic function has a minimum value or maximum value. Then find the coordinates of the minimum or maximum point.
19.f(x) = x2 - 2x + 1
And how you would complete the square when I have f(x) = 2x2 - 4x

completing the square
2(x^2 -2x +1 -1)
f'=2x-2 set that to zero. solve for x.
Now use the second derivative test...
f"=2, positive, so the conclusion is that it is ....
I will be happy to critique your thinking

2x2-16x+4 = i do not know
