Unit 2 lesson 8 cumulative practice problems
1. match each polynomial with its end behavior. some end behavior options may not
have a matching polynomial.
a. f(x) = 2x3 + 3x4 + x2 - 1
b. f(x) = 1 - 3x + x2
c. f(x) = 9+ x4
d. f(x) = 2x + 5
a.
as x gets larger and larger in either the positive or negative direction, f(x) gets
larger and larger in the positive direction.
b.
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.
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.
c.
d.
as x gets larger and larger in either the positive or negative direction, f(x) gets
larger and larger in the negative direction.
walan nate larger and larger in the negative direction as x gets
