Answer 1

it is a rational function.. what do you need to do ?

Answer 2

What are the excuded values?

Answer 3

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

Answer 4

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

Answer 5

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..

Answer 6

yes, that is what you are looking for..
