I'm not sure what the denominator of your rational function is?
\n" ); document.write( "Are you missing an operator? +? -? Or is it really $\"x%5E3%2A25x=25x%5E4\"$
\n" ); document.write( "The domain is all $\"x\"$ values for which the function is defined.
\n" ); document.write( "For rational functions (in simplest terms), when the denominator equals zero, the function is undefined.
\n" ); document.write( "So look for values of $\"x\"$ that make the denominator equal zero.
\n" ); document.write( "If your denominator is $\"25x%5E4\"$ , then $\"x=0\"$ is a value that is not in the domain.
