Answer 2

thanks but those the negative make any changes to the graph?

Answer 3

yes, the way I look at the negative sign is like this ... say the horizontal line is a "hub", so I push one of the "humps" and it "swivels" around it 180 degrees, so the "hump" above ends up at the bottom and the bottom "hump" ends up at the top :)

so, now give a push to the hump :)
