\n" ); document.write( "\n" ); document.write( "Write an equation for a rational function with:
\n" ); document.write( "Vertical asymptotes at \"x+=+-6\" and \"x+=+-4\"
\n" ); document.write( "x intercepts at\"+x+=+-1\" and\"+x+=+-3\"
\n" ); document.write( "Horizontal asymptote at\"+y+=+7\"\r
\n" ); document.write( "\n" ); document.write( "a rational function: \r
\n" ); document.write( "\n" ); document.write( "\"f%28x%29=p%28x%29%2Fq%28x%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "given: \"x\" intercepts at \"x+=+-1\" and \"x+=+-3\"\r
\n" ); document.write( "\n" ); document.write( " the x -intercepts exist when the numerator is equal to \"0\"\r
\n" ); document.write( "\n" ); document.write( "\"p%28x%29=%28x-%28-1%29%29%28x-%28-3%29%29\"
\n" ); document.write( "\"p%28x%29=%28x%2B1%29%28x%2B3%29\"

\n" ); document.write( "\n" ); document.write( "To find the vertical asymptote(s) of a rational function, simply set the denominator equal to \"0\" and solve for \"x\". \r
\n" ); document.write( "\n" ); document.write( "you are given vertical asymptotes at \"x+=+-6\" and \"x+=+-4\", so denominator is\r
\n" ); document.write( "\n" ); document.write( "\"q%28x%29=%28x-%28-6%29%29%28x-%28-4%29%29\"\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so far \"f%28x%29=%28x%5E2+%2B+4+x+%2B+3%29%2F%28x%5E2+%2B+10+x+%2B+24%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you are given horizontal asymptote at \"y+=+7\", and then the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is the ratio of the leading coefficients \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, your function is\r
