Best ResponseYou've already chosen the best response.0I'm studying for a call and my teacher says the key points I should go over are (his words): "solving quadractics and what do the graphs do" What exactly does he mean by "what do the graphs do"?

Best ResponseYou've already chosen the best response.0I know HOW to solve quadratic graphs and how to read them but... what do they do? what're they there for?

Best ResponseYou've already chosen the best response.0Um I think your teacher meant relating the graph to the equation. Solving quadratic equations gives you roots, which sometimes you'd get No Real Roots, or Two Real Roots, or One Real Root Given \(ax^2+bx+c=0\), using b^24ac dw:1380216159086:dw dw:1380216208509:dw dw:1380216228972:dw No Real Roots, b^24ac<0 Two Real Roots, b^24ac>0 One Real Root, b^24ac=0

Best ResponseYou've already chosen the best response.0^ that's something i can consider, okay. all i'm looking for (sam and others) is just a statement like that. are quadratic graphs used to plot things, show how to get a value... what.

Best ResponseYou've already chosen the best response.0Solving quadratics mean solving for x right? \[x=\frac{ b \pm \sqrt{b ^{2}4ac} }{ 2a }\] I assume you know the above equation? That's where the b^24ac comes from. The roots are the solutions for x.

Best ResponseYou've already chosen the best response.0yes.... that has nothing to do with graphs, though .. i'm thinking graphs, in general, are just used to plot things and show an explanation
