Let f(x, y)equals=x squared minus xy plus y squared minus yx2−xy+y2−y. find the directions u and the values of upper d subscript bold uduf(1,minus−1) for which the following is true. a. upper d subscript bold uduf(1,minus−1) is largest b. upper d subscript bold uduf(1,minus−1) is smallest c. upper d subscript bold uduf(1,minus−1)equals=0 d. upper d subscript bold uduf(1,minus−1)equals=4 e. upper d subscript bold uduf(1,minus−1)equals=minus−3

answer: x

step-by-step explanation:

any options?

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
