Are trying to do this with algebra?

it can be done by graphing or algebra. i graphed it with graphcalc but can't seem to zoom in properly to find out these features

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.

5. 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.
