@amistre64

anonymous · Answer

I think its A or C

amistre64 · Answer

-4/(4x+8) * 5(x+3)/(x^2-9)

now, the domain doesnt change just because we simplify out some "common factors".

the domain is defined by the original setup, not its simplification.

amistre64 · Answer

A and C are not defining the correct domain

anonymous · Answer

Is it D?

amistre64 · Answer

your guessing now?  or was A and C a guess as well?  what is your simplificaton?

amistre64 · Answer

the error in A and C was the domain ... which is why i pointed it out.  D is no where like A or C ...

anonymous · Answer

My mom says its A

anonymous · Answer

A,B,C have the correct simplification 
I think the domain is all x except x=0 can't divide by zero
