\n" ); document.write( "\n" ); document.write( "If your function crosses the -axis at 2, then the numerator polynomial must have a zero at 2. Hence, one factor of the numerator is \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If your function just touches the -axis at -1, then the numerator polynomial must have a zero at -1 with a multiplicity of 2. Hence, another factor of the numerator is \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If the function must have a vertical asymptote at -5, then the denominator polynomial must have a zero at -5. Hence a factor of the denominator must be .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Likewise, for a vertical asymptote at 6, the denominator must have a factor of .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In order for there to be a horizontal asymptote other than the -axis, the degree of the numerator and denominator polynomials must be the same and the ratio of the lead coefficients must be equal to the value of the -coordinate of the ordered pairs in the asymptote.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In order to accomplish equal degree, we need to double up on one of the factors in the denominator. I choose the , hence the first factor fo the denominator becomes \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In order for there to be a 3 to 1 ratio between the lead coefficients on the numerator and denominator such that the horizontal asymptote occurs at , insert a factor of 3 into the numerator.\r
