Algebra.Com's Answer #586758 by josgarithmetic(39620)![]() ![]() ![]() You can put this solution on YOUR website! Information for better guidance:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x-intercepts are the same as ROOTS or ZEROS for the function, which appear in the numerator. Think, \"binomial factors\".\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Horizontal asymptote means that the degree of numerator and denominator are equal.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You correctly chose degree two for numerator and denominator. The horizontal asymptote means that the leading terms of numerator and denominator become increasingly important as x goes to the left or the right unbounded, and the ratio of their coefficients will approach \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "That should be enough to make the proper adjustments. You almost have it. \n" ); document.write( " |
