You know that so that . (i.e: wherever you see , replace it with ). Expand the square and write out all the terms.

Coordinate of y when x = x is 3x2+1

The question is asking you to replace x here with x+dx and expand to get this new y coordinate (y+dy) in terms of x and dx

Please do not tag so many people at the same time.

As you can see 3 separate people have gone through the effort of answering the same question and that is unnecessary time wasted.

EDIT: KtA has now deleted his answer having seen 2 other people answer the question, which just wastes his time.
