Question

infinite limits question about how to demonstrate work

Answer 1

(x^4+x^5) lim x-> -infinity

Answer 2

my first thought was to factor out x^4

Answer 3

are you sure the question is correct

Answer 4

\[x^4(1+x)\]

Answer 5

i mean there are no denominators and numerators ?

Answer 6

nope

Answer 7

oh wait

Answer 8

i wouldnt even have to do that

Answer 9

if thats the case, then you can do much here, what you have done is absolutely correct , simply put x= - infinity

Answer 10

your answer should be - infinity or DNE

Answer 11

\[-\infty^4+-\infty^5 = \infty + (-\infty)\]

Answer 12

=0?

Answer 13

no i meant x^4(1+x) is correct, then you can say that as x approaches - infinity, the limit approaches to -infinity

Answer 14

you CAN NEVER SAY the answer is 0,

Answer 15

We do not know infinity, and -infinity as well, so can never call it 0

Answer 16

does that help?

Answer 17

ok

Answer 18

yep sure does
