This is a great question, but it's also a very broad one. Please find and post one or two actual rational expressions, so we can get started on specifics of how to find vertical and horiz. asymptotes.
In the case of vert. asy.: Set the denom. = to 0 and solve for x. Any real x values that result indicate the location(s) of vertical asymptotes.
Hi!
So we know that he has 20 candy bars.
= 20
He wants to give 2 to each friend. So 2 candy bars x friends.
2f
He's going to keep 10.
+10
Put all of the parts together.
2f + 10 = 20
The answer is 2f + 10 = 20
Hope this helps!
