Question 927566
{{{(x^2-2x-3)/(x+17)}}}
x cannot equal -17 since you cannot divide by zero. In graphical terms, this means a vertical asymptote of x=-17
a) Domain ( {{{-infinity}}}, -17) U (-17, {{{infinity}}}) 
b) x= -17
c) y= x-19 
*[illustration sol_927566].
d)Although this graph shows a good example, it does not show the second part of the graph starting from -17 to {{{-infinity}}}. So, keep in mind that you need to draw the second graph as well using the asymptote equations given.
{{{graph(400,400,-25,25,-25,25,(x^2-2x-3)/(x+17))}}}
hope this helps!
