Match the polynomial with its end behavior.

Draggable item		Corresponding Item
f(x)=1-x^{2}+2x^{3}		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)=7-x^{4}		As x gets larger and larger in the positive direction, f(x) gets larger and larger in the positive direction. As x gets larger and larger in the negative direction, f(x) gets larger and larger in the negative direction.
f(x)=-2x+3		As x gets larger and larger in the positive direction, f(x) gets larger and larger in the negative direction. As x gets larger and larger in the negative direction, f(x) gets larger and larger in the positive direction.
f(x)=x^{2}-6x+3		As x gets larger and larger in either the positive or negative direction, f(x) gets larger and larger in the negative direction.
