Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
I'm going to presume you mean:
\ =\ \frac{4}{9\ -\ 7x})
which is a rational function since it is the ratio of two polynomials. The domain of a rational function is the set of real numbers excluding any value that would make the denominator equal zero.
To determine the values to be excluded from the domain, set the denominator of your function equal to zero. The zero(s) of the denominator polynomial are the values to exclude.
