On the extremum of function: y = x-lnx, the correct conclusion is that () a has a minimum 1, B has a maximum 1, C has a maximum E-1, D has a minimum E-1 reason

On the extremum of function: y = x-lnx, the correct conclusion is that () a has a minimum 1, B has a maximum 1, C has a maximum E-1, D has a minimum E-1 reason

y=x-lnx (x>0)
y'=1-1/x (x>0)
(0,1),y0
Therefore, the first single reduction, then monotonous increase
Minimum point x = 1, y = 1
