Y-Coordinate of the focus of the parabola of a Quadratic Function


A parabola is a graph of a quadratic function, such as y=ax^2+bx+c. A parabola is the set of all points equidistant from a point that is called the focus of the parabola and a line that is called the directrix of the parabola. Y-coordinate of the focus can be calculated by the “a”, “b” and “c’ coefficients of the function.
