Will someone please help me on this? I do not no how to do it at all.
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
To find the domain, you must make sure the denominator does NOT equal zero. In this case, make sure that 4-9x does NOT equal zero.

To solve this, solve
4-9x=0 and the domain will be all values of x EXCEPT this value!
4=9x
x=4/9

Domain is all values of x EXCEPT 4/9.
