Question 6758: help me find the domain of how and why?

Answer by ichudov(507) (Show Source): You can put this solution on YOUR website!
The domain is simply all points where the function is defined. The only way this one can be UNdefined is when the denominator is 0.
x+4 = 0 x=-4.
So, the domain is all values of x EXCEPT -4.
