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)

2(x-1)^2 -2

19.

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
