anonymous · Answer

anonymous · Answer

What are the excuded values?

anonymous · Answer

it is the zeros of the denominator...
because if the denominator is equal  zero, the function will become undefined..

anonymous · Answer

my options are x=7 x=-9 x=9 or none of the above

anonymous · Answer

your denominator is x-9 right?
so set it like this,
x-9=0
then solve for x, whatever you get for x, it will be the zeros of the denominator and therefor, it is the restriction..
