Quadratic Graphs

Instructions
Use the sliders to modify the values of the coefficients [math]a[/math], [math]b[/math] and [math]c[/math]. [br][br]Observe the graph of [math]y=ax^2+bx+c[/math] and answer the questions that follow.[br][br]Tick the boxes to show/hide [math]x[/math]-intercept, [math]y[/math]-intercept, turning point and line of symmetry.
Multiple Choice (multiple answers)
