here are the problems :

campbell_st · Answer

the easiest way yo look at horizontal asymptotes is to look at the leading terms 
in the numerator and denominator

if they are the same degree the the horizontal asymptote will be the coefficients 
of the leading terms...

in your 1st question  you have      7x 
                                                   ---
                                                   2x

so the horizontal asymptote is 7/2  

when the degree of the numerator is greater than the denominator the asymptote will be oblique 

and needs polynomial division or synthetic division to find it. 

if the degree of the numerator is less than the denominator the asymptote may by y = 0

hope this helps

so for the first question, its c right? because its not oblique

anonymous · Answer

*** it is oblique

campbell_st · Answer

thats correct... same degree.. so use the coefficents of the leading terms

for the next question, you are asked for the horizontal... as the degree is different... numerator higher... is will have an oblique

the last needs some division.
