Question #650bf

Answer 1

`lim_(x rarr -oo) -2x^4+3x^3-1 = -oo`

Explanation:

An easy way to confirm this is to look at every term and the operations between them.

As `xrarr-oo`, `-2x^4` is negative and `3x^3` is also negative.

So as `xrarr-oo`, we are adding two negative numbers and subtracting a positive number. This means that `yrarr-oo` as well.
