1. Match each polynomial with its end behavior. Some end behavior options may not have a
matching polynomial.
a. f(x) = 2x3 + 3x+ + x2-1
A. As x gets larger and larger in either the positive
or negative direction, f(x) gets larger and
b. f(x) = 1 - 3x + x2
larger in the positive direction. (Up, Up)
B. As x gets larger and larger in the positive
c. f(x) = 9+ x4
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
d. f(x) = 2x + 5
larger in the negative direction. (Down, Up)
C. 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. (Up, Down)
D. As x gets larger and larger in either the positive
or negative direction, f(x) gets larger and larger
in the negative direction. (Down, Down)
