Using limit concepts, the matching pairs are:
A - 3
B - 1
C - 2
D - 4
The end behavior of a function f(x) is given by it's <u>limit as x goes to infinity.</u>
Function A:
, then:


Thus, inverse directions, so matching pair with 3.
Function B:
, then:


Always positive, so matching pair with 1.
Function C:
, then:


Same directions, thus, matching pair with 2.
Function D:
, then:


Always negative, so matching pair with 4.
