Algebra.Com's Answer #308706 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! the \"domain\" specifies all the values that x can take for the given function: \n" ); document.write( "-5 times the square root of x \n" ); document.write( "or \n" ); document.write( " \n" ); document.write( "In this case, you just don't want the value under the radical to be negative (otherwise the result is an imaginary number). \n" ); document.write( "So, the domain is \n" ); document.write( "all real numbers equal to or greater than zero \n" ); document.write( "OR \n" ); document.write( "[0, +oo) \n" ); document.write( "where \n" ); document.write( "+oo is positive infinity \n" ); document.write( " |
