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