Second-Order Polynomial
Drag the sliders to change a₀, a₁, a₂ and watch the curve update in real time.
A second-order (quadratic) polynomial has the form y = a₀ + a₁x + a₂x²:
- a₀ — vertical offset (DC level)
- a₁ — linear slope
- a₂ — curvature: positive opens upward, negative downward. Set to 0 for a straight line.
