Hi!

Im making an

applet to graph a quadratic function...now im not going to be rude and say "tell me how to do it!" but i was just wondering if i could get some assistance on making it...

Now of course, i've had a go at it, and i've made an applet to display the z intercepts, y intercept, and vertex (turning point). This is determined by the user inputs of the three coefficients a, b, and c.

First question, is this all the information i will need?

Secondly, i am struggling to figure out how to put this information into a graph and make it a parabola...

Thank you very much for your help!

Ps. my applet is below if you wish to have a look, i've made a crude graph if that helps as well...
