Graph it in the largest possible window yu can, and the go to zoom in. place the curser over a point of interest, and the press enter until you can clearly see the features.

graph attached ...

Try the window

Xmin=-6
Xmax=6
xscl=1
Ymin=-100000
Ymax=100000
Yscl=10000

Ymin and Ymax way too large ... results in hidden behavior.

recommend Ymin = -200 and Ymax = 600.
