Question 912014
Help here is just for the first equation.


The x intercepts are for {{{20x(x+36)=0}}}
{{{x(x+36)=0}}}
{{{highlight(x=0)}}}  or {{{highlight(x=-36)}}}


y axis intercept goes through the <b>origin</b>, as you can find when x=0.


Horizontal Asymptote:  Degree of numerator and denominator are 2; so at either unbounded extreme, y approaches 20.  {{{highlight(y=20)}}}, the horizontal asymptote.


Vertical Asymptotes:   The denominator shows y is undefined for {{{highlight(x=18)}}} and for {{{highlight(x=1)}}}; and these are not represented as factors in the numerator, so they are the vertical asymptotes.
