Hi Guys!

Can someone help me?

I have found interesting question and thing that official explanation contains a mistake:

Is x^3-6x^2+11x-6≤0?

(1) 2<x<3

(2) 2≤X<3

The roots of the inequality are: 1, 2 and 3.

See below:

1) First statement refers to positive sector from 1 to 2 exclusively, so the data tell us that inequality is positive – sufficient!

2) Second statement tells us that in region from 2 to 3 exclusively the inequality is negative, in point 2 it is equal to 0. Since we have “≤” both is acceptable – sufficient!

Hence, my answer is D.

Unfortunately the official answer is A!
