Question

Check my answer?  Is this a polynomial? (picture below)

anonymous · Answer

(A) This is not a polynomial.  The entire graph is on one side of the vertical axis.
(B) Yes, this graph represents a polynomial.  There are two turning points and the least degree possible is two.
(C) This is not a polynomial.  There are no turning points.
(D) Yes, this graph represents a polynomial.  There is one turning point and the least degree possible is two.


I think it's A because every polynomial I've seen crosses through the y axis, can anyone confirm?

danjs · Answer

yes it is, and it has one turning point, least degree 2

danjs · Answer

2 zeroes

danjs · Answer

every polynomial that looks like that will cross the y axis eventually, the ends go on forever

danjs · Answer

even if it is at y = fifty million   it still will
