These really confuse me..so can someone explain the whole thing itself to me as simple as possible?
Hi dropkikkmarc71,
That's a tall order. You should be able to find good explanations in advanced algebra books. You could try to google for some sites. I found this one that might be helpful:
Graph Piecewise Functions
And there are some nice powerpoint slides here:
