Answer:

#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.
