(x-4)/(x+5)>=3
\n" ); document.write( "x cannot be -5 because the denominator would be 0. The vertical asymptote is -5.
\n" ); document.write( "(x-4)/(x+5)=3
\n" ); document.write( "x-4=3x+15 turn the inequality into an equation.
\n" ); document.write( "2x=-19
\n" ); document.write( "x=-9.5
\n" ); document.write( "Now we look at a graph of x-4/x+5 and find out where it is equal to or greater than 3.
\n" ); document.write( "We see that the only area where y>=3 is where -9.5<=x<-5 or x[-9.5,-5) ans.
\n" ); document.write( "When x>0 y<1
\n" ); document.write( "The horizontal asymptote is 1.
