Show the graph of y = ax² + bx + c. Three sliders: a (-5 to 5), b (-10 to 10), c (-10 to 10). As the student adjusts: a>0 opens up, a<0 opens down. c moves the vertex up/down. b shifts the parabola left/right. Highlight key features: vertex (peak/valley), axis of symmetry, x-intercepts (roots). The
