Find a

as **x** approaches **a = 2** for various values of epsilon starting with **e = 0.5**.

In the following LiveMath Notebook, you can see the graph of

Explore with changing **a**; consider **a = 6, 8, 16** using the same epsilon's. Can you detect a pattern?

Change the slope and **y**-intercept and consider **a = 6, 8, 16** using the same epsilon's again. Can you detect a pattern?.
