look at the denominator ...

are you familiar with the rule that says division by 0 is undefined?

if , what would be the value of the denominator?

so ... what does that tell you cannot be equal to ?

domain is the set of all x-values that can be input into a function without breaking certain rules ... division by 0 is one of those rules that cannot be broken. - December 9th 2008, 06:05 PMDHS1
