Algebra.Com's Answer #453633 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! The denominator is also y*(y-4). \n" ); document.write( "y can be of the real numbers so that \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Your use of 'y' as the independent variable in the function f indicates that the domain must be for y. The intent to use y instead as the dependent variable would be very dubious for the given rational function. \n" ); document.write( " |
