what is the domain for f(x)
f(x)= x/(x+2)

Math 
Reiny,
the big "nono" in math is division by zero.
so the domain would be all values of x except the number which would make the denominator zero.
So tell me what you would state as the domain.

bobpursley,
Well, x cannot be 2, can it?

Math 
Crystal,
so x can be everything except 2 because 2+2=0

Math 
bobpursley,
correct.
