Minimum value as the parabola is like the letter "U".
dy/dx = 2x-2
So we want the gradient to be 0. 0 = 2x-2
x = 1
So the minimum value is y=1.
The graph confirms this:

since the coefficient of the squared term is positive, this is an upward-opening parabola

it has a minimum value (the vertex; located at (1,1))
