```
sage: f(x)=(4*3+3*x)/(-12+2*x)
sage: f.limit(x=Infinity)
3/2
```

or

```
sage: g=(4*3+3*x)/(-12+2*x)
sage: g.limit(x=Infinity)
3/2
```

or with $f$ and $g$ defined as above,

```
sage: limit(f, x=Infinity)
3/2
sage: limit(f(x), x=Infinity)
3/2
sage: limit(g, x=Infinity)
3/2
```

You can also leave out the asterisks:

```
sage: implicit_multiplication(True)
sage: g=(12+3x)/(-12+2x)
```

SAT Math Level 2 Subject Test Sample Question #26

Problem evaluating limit: assume doesn't work!

Why is Sage calling 1 a variable?

Detecting extrema and asymptotes of (nasty) functions of two variables

How I can evaluate the limit superior of a sequence?
