    I'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"?

    I know HOW to solve quadratic graphs and how to read them but... what do they do? what're they there for?

    I would retriceume you use the graphs to plot the stufff?

    I thought there'd be something more complex to it...

    Give a question? My question is posted @08surya Unless you mean an equation. I don't know why you want one....

    Um 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^2-4ac |dw:1380216159086:dw| |dw:1380216208509:dw| |dw:1380216228972:dw| No Real Roots, b^2-4ac<0 Two Real Roots, b^2-4ac>0 One Real Root, b^2-4ac=0

    graph shows we r going to get the value of equation or not

    ^ 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.

    Solving 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^2-4ac comes from. The roots are the solutions for x.

    yes.... that has nothing to do with graphs, though .-. i'm thinking graphs, in general, are just used to plot things and show an explanation
