Leading term test for polynomial end behavior :
\The end behavior of any non-constant polynomial function
can be described in one of the following four ways, as determined by the degree
of the polynomial and its leading coefficient
.
For
odd and
positive :
and
.
For
odd and
negative :
and
.
For
even and
positive :
and
.
For
even and
negative :
and
.
Observe the graph of the function :
\The end behavior of the graph is
and
.
So the degree of the polynomial function
is odd and leading coefficient
is positive. \ \
is odd and
is positive.
