Algebra.Com's Answer #823634 by Theo(13342)![]() ![]() You can put this solution on YOUR website! the domain is all real values of x that lead to a real value of f(x). \n" ); document.write( "you have f(x) = 3/(x+9) \n" ); document.write( "since (x+9) is in the denominator, then the denominator will be equal to 0 when x = -9. \n" ); document.write( "the value of f(x) = 3/(x+9) is not defined when the denominator is equal to 0. \n" ); document.write( "the domain of the function is therefore all values of x except at x = -9. \n" ); document.write( " \n" ); document.write( " |
