The graph of a quadratic function is a parabola. The range is restricted to those points greater than or equal to the A quadratic function is a function of degree two. Quadratic functions generally have the whole real line as their domain: any Is the set of all the output values (values of values for which the function is defined, and the If the equation is in standard form, then you can just take intercept of a parabola simply by entering So, the axis of symmetry is the vertical line ![]() You can see how this relates to the standard equation by multiplying it out: In this equation, the vertex of the parabola is the point The equation for a parabola can also be written in "vertex form": " shape (or the top, if the parabola opens downward). Of a parabola is the point at the bottom of the " Is positive, the parabola opens up otherwise it opens down. In the general equation is to make the parabola "wider" or "skinnier", or to turn it upside down (if negative): The general form of a quadratic function is
