Create Free AccountA quadratic function has the form f(x) = ax² + bx + c, where a ≠ 0. The x² term makes it quadratic. Its graph is a U-shaped curve called a parabola. The second differences are constant (unlike linear functions where first differences are constant).
Linear: constant rate of change (straight line). Quadratic: rate of change itself changes at a constant rate (parabola). Exponential: multiplies by a constant factor (curved, eventually grows faster than quadratic).
