Homework Help: Calculus

Posted by Eric on Monday, October 10, 2011 at 6:30pm.

Could someone please help me on this question where you find the limit. I'm having a test tomorrow and I'm a little confused.

lim -x/√(4-x^2)
x-->-2+

Any help would be greatly appreciated. Thanks in advance!!

The numerator approaches 2.
The denominator has no real value if x>2.

So, there is no limit defined as x -> 2+

The function is not defined for any x>2.
