Quadratic Function Calculator

About: Quadratic Function Calculator

A univariate (single-variable) quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape, whose axis of symmetry is parallel to the y-axis,
