You can put this solution on YOUR website!
f(x) = y = (2x) / (x + 4)
\n" ); document.write( "Intercepts:
\n" ); document.write( "x intercept (when y=0):
\n" ); document.write( "2x/(x+4)=0
\n" ); document.write( "2x=0 multiply each side by (x+4)
\n" ); document.write( "x=0
\n" ); document.write( ".
\n" ); document.write( "y intercept (when x=0)
\n" ); document.write( "0/4=y
\n" ); document.write( "y=0
\n" ); document.write( ".
\n" ); document.write( "vertical asymptote (when the denominator=0):
\n" ); document.write( "x=-4
\n" ); document.write( ".
\n" ); document.write( "horizontal asymptote:
\n" ); document.write( "When the numerator and denominator have the same degree we use this formula: a[m]/b[n]=2/1=2
