what are the different graph and plots for quadratic equations in certain condition like a>0, D<0.(somethings like a parabola without open side, toching x axis etc)
what are the number and nature of roots and what do these graphs tell us about the equations.
Also, please suggest any book, pdf or website where i can get these graphs. Currently i have Higher Algerbra by Hall & Knight which does not have these graphs.
