The Quadratic Function when geometrically plotted on Cartesian coordinate system the roots of a
Quadratic function is defined as the points where the function‟s plot intersects the X-axis. When the Quadratic
equation of the function is solved the X-intercept values are the solution of the Quadratic Equation. However
some Quadratic equations do not give real solutions. Instead the solutions contain square root of negative
quantities. Algebraic representation of this solution is defined considering the square root of negative quantities
as imaginary number „i‟. Geometrically these are the Quadratic functions whose plots never intersect the X-axis.
