Question

The end behavior of  most closely matches which of the following? 

Options:

1. y = 5
2. y = 2
3. y = 1
4. y = 0

Answer 1

As x goes to infinity ( + or -), we have an undefined solution.

So..try L'Hopital's rule:

1st derivative of top and bottom:

4x/2x = 2

So 2 is the limit of the original function. (Verify by graphing)
