Question

determine: lim 5-n^2/2n
x→∞

Answer 1

We seem to be confusing our variables...

Answer 2

if the problem is correctly written, then it's 5-n^2/2n

Answer 3

It seems to me that the limit is -Infinity

Answer 4

as x approaches infinit?

Answer 5

yes

Answer 6

The expression is equivalent to -n/2 for large n.

Answer 7

So the limit as n approaches infinity is - infinity

Answer 8

yes

Answer 9

but problem is as x approaches infinty

Answer 10

are you sure as x approaches infinity. Your expression does not depend on
x. So x does not have any effect on your expression and in the case, the limit
would be your expression as written.
