A3. Which of the following expressions has the smallest value for $x=11$?
(A) $-x^{2}+x$
(B) $-x^{2}+x-12$
(C) $(-x)^{2}-x$
(D) $(-x)^{2}-x+12$
(E) $(-x)^{2}-12$
A3. For $x=11$ the values of the following expressions are: $-x^{2}+x=-110, -x^{2}+x-12=-122, (-x)^{2}-x=110, (-x)^{2}-x+12=122, (-x)^{2}-12=109$. The expression with the smallest value for $x=11$ is $-x^{2}+x-12$.
