cube
,
forming
a
relationship
between
these
two
geometric
shapes

a straight line that a curve approaches indefinitely but never intersects, characterizing the limiting behavior of the curve
Ex:
A
horizontal
asymptote

when
the
values
of
a
function
approach
a
constant
as
the
input
goes to
positive
or
negative
infinity
