=
a
x
n

x
m
R
(
x
)
=
a
x
n
b
x
m
where
n
n
is the degree of the numerator and
m
m
is the degree of the denominator.
1. If
n
<
m
n
<
m
, then the x-axis,
y
=
0
y
=
0
, is the horizontal asymptote.
2. If
n
=
m
n
=
m
, then the horizontal asymptote is the line
y
=

b
y
=

.
3. If
n

, then there is no horizontal asymptote (there is an oblique asymptote).
Find
n

Since
n

, the x-axis,
y

y
=

, is the horizontal asymptote.
y
=

There is no oblique asymptote because the degree of the numerator is less than or equal to the degree of the denominator.

Answer:
1) 10^2 + 1
2) ?
3) 2(3^3) + 11
4) 16^2 - 79
Step-by-step explanation:
1) 101 = 100 +1 = 10^2 +1
2) ?
3) 173 = 81+81+11 = 3^3+3^3+11 = 2(3^3) +11
4) 177=256-79 = 16^2 -79
