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

Column A
1.
f(x) = 2x3 + 3x4 + x2 - 1

:
f(x) = 2x3 + 3x4 + x2 - 1

2.
f(x) = 1 - 3x + x2

:
f(x) = 1 - 3x + x2

3.
f(x) = 9 + x4

:
f(x) = 9 + x4

4.
f(x) = 2x + 5:
f(x) = 2x + 5
Column B
a.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 teh negative direction.
b.As x gets larger and larger in either the positive or negative direction, f(x) gets larger and larger in the positive direction.
