Algebra.Com's Answer #637957 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! the domain is restricted by where the denominator cannot be 0. The numerator may be any number. \n" ); document.write( "sqrt (9-x^2) cannot be 0 \n" ); document.write( "That means 9-x^2 cannot equal 0. \n" ); document.write( "x^2=9 will make the denominator 0 \n" ); document.write( "x of +/- 3 will make the denominator 0 and cannot be in the domain. \n" ); document.write( "(-oo,-3),(-3,3) and (3,oo) are the domain. \n" ); document.write( " |
