Algebra.Com's Answer #22526 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! find the domain of the following functions by determining which numbers, if any, cannot be used: \n" ); document.write( "1) f(x)=3x^2/(1+3x)\r \n" ); document.write( "\n" ); document.write( "The denominator cannot be zero. \n" ); document.write( "So x cannot be -1/3. The domain is all Real numbers except x=-1/3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2) f(x)=(x^2+x-2)(x^2+4) \r \n" ); document.write( "\n" ); document.write( "This denominator is never zero \n" ); document.write( "So, domain is all Real Numbers.\r \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
