Question

lim x >-inf x^5-5000x^4/2x^5 + 7000 Estimate the limit numerically

Answer 1

numerically? so bust out your dusty calculator, plug in really large negative values, and try to get an idea of what the limit is approaching.

Answer 2

Thanks I was not going big enough!!

Answer 3

\[\lim_{x \rightarrow -\infty} (x ^{5} - x ^{4}5000) / 2x ^{5}+7000\]
\[=\lim_{x \rightarrow -\infty} (( x ^{5}) (1-5000/x))/ x ^{5} (1+7000/x ^{5})\]

Answer 4

cancel out x^5 and plug x = - infty

your answer is approx 1/2

Answer 5

I got 2.1
does that sound right??

Answer 6

0.5
