Question

Limits~

Answer 1

Looking at it, what do you think that it would be?

Answer 2

\(\large{\lim\limits{_{x\rightarrow -\infty}} (x^2+x^3)}\)

Answer 3

Hmm, -1?

Answer 4

Try substituting \(-\infty\) in.

Answer 5

Well that would give us 0.. but our professor said we can't do infinty-infinity xD

Answer 6

\(((-\infty)^2+(-\infty)^3)=-\infty+(-\infty)=-\infty\)

At least that is my thought.

Answer 7

Well, Don't I feel like a fool now xD
Thanks Austin!

Answer 8

No problem :)

Answer 9

Oh, and Wolfram agrees :)

Answer 10

That actually reminded me of "end behavior"

Answer 11

\[\lim_{x \rightarrow -\infty}x^2(x+1)\]
According to this product we have a positive times a negative so we will have a negative product for sure.
As x gets negative large x^2(x+1) gets negative large.

Answer 12

Wait, I made a silly math error earlier, but you still get the idea :$
