Determine the domain and range of a quadratic function y = ax² + bx + c. Shows interval notation for both.
Determine the domain and range of a quadratic function y = ax² + bx + c. Shows interval notation for both.
Coefficient of x².
Coefficient of x.
The constant term.
For a quadratic, domain is always all real numbers. Range depends on the sign of a: if a > 0, range is [k, ∞); if a < 0, range is (-∞, k], where k is the vertex y-coordinate.
