f(x)=1-3x+x^{2}		As x gets larger and larger in either the positive or negative direction, f(x) gets larger and larger in the positive direction.
f(x)=2x+5		As x gets larger and larger in the positive direction, f(x) gets larger and larger in the positive direction. As gets larger and larger in the negative direction, f(x) gets larger and larger in the negative direction.
f(x)=2x^{3}+3x^{4}+x^{2}-1		As x gets larger and larger in the positive direction, f(x) gets larger and larger in the negative direction. As gets larger and larger in the negative direction, f(x) gets larger and larger in the positive direction.
f(x)=9+x^{4}		As x gets larger and larger in either the positive or negative direction, f(x) gets larger and larger in the negative direction.

A polynomial function, f(x), has x-intercepts at (-6,0) and (2,0). What is one possible factor of f(x)?

Match each polynomial with its end behavior. Some end behavior options may not have a matching polynomial.

Which polynomial function gets larger and larger in the negative direction as x gets larger and larger in the negative direction?

The graph of a polynomial function f is shown. Which statement about the polynomial is true?
