Determine whether the following limit is a number, or infinity or -infinity.

Can anyone help me with this?

Answer 1

so when taking a limit like this to infinity, check the highest exponent on top and bottom
if top is greater it approaches +/- infinity
if they are equal, it approaches a number

Answer 2

check signs to see if it would be + infinity or -infinity

Answer 3

oh it's -1 lol thanks

Answer 4
