Quadratic Function - The Square Root of A Quadratic Function

The Square Root of A Quadratic Function

The square root of a quadratic function gives rise to one of the four conic sections, almost always either to an ellipse or to a hyperbola. If then the equation describes a hyperbola. The axis of the hyperbola is determined by the ordinate of the minimum point of the corresponding parabola .
If the ordinate is negative, then the hyperbola's axis is horizontal. If the ordinate is positive, then the hyperbola's axis is vertical.
If then the equation describes either an ellipse or nothing at all. If the ordinate of the maximum point of the corresponding parabola is positive, then its square root describes an ellipse, but if the ordinate is negative then it describes an empty locus of points.

Famous quotes containing the words square, root and/or function:

    I would say it was the coffin of a midget
    Or a square baby
    Were there not such a din in it.
    Sylvia Plath (1932–1963)

    She saw a dust bearing bee sink into the sanctum of a bloom; the thousand sister calxes arch to meet the love embrace and the ecstatic shiver of the tree from root to tiniest branch creaming in every blossom and frothing with delight. So this was a marriage!
    Zora Neale Hurston (1891–1960)

    My function in life is not to be a politician in Parliament: it is to get something done.
