Graph y = ax² + bx + c with three sliders for a, b, c. Slider a: -3 to 3 (changes width and direction). a>0 opens up, a<0 opens down. |a| large = narrow, |a| small = wide. Slider b: -5 to 5 (shifts vertex left/right). Slider c: -5 to 5 (shifts up/down, is the y-intercept). Display: vertex coordinate
