What is the end-behavior function for each of the following functions? Homework Help ✎

About end behavior:

End behavior describes the shape of the function if we ignore all vertical asymptotes and holes.

If the function has a horizontal asymptote, then that is its end behavior.

If a function has a slant asymptote, then that is it's end behavior.

If a function oscillates as or

*, then it has no end behavior.*

For rational functions, end behavior can often be found using polynomial division (and ignoring the remainder).
