Y = x & # 178; - 2x + 2, X ∈ [T, t + 1], find the maximum value of function (expressed by T)

Y = x & # 178; - 2x + 2, X ∈ [T, t + 1], find the maximum value of function (expressed by T)

I'll give you a detailed answer to the discussion of axis of symmetry. I hope I can try it next time, because it's very important
f(x)=(x-1)²+1
The axis of symmetry x = 1, we should draw a graph to discuss the relationship between the interval [T, t + 1] and the axis of symmetry
1) When t + 1
