Domain Of A Parabola Definition
A fixed straight line the directrix.
Domain of a parabola definition. It is easy to find the domain and range of a parabola when the graph of the same is given unlike when the equation is given. A parabola is the graph of a quadratic function or a function of the form f x ax2 bx c. The graph of a quadratic function is a u shaped curve called a parabola.
In mathematics a parabola is a plane curve which is mirror symmetrical and is approximately u shaped. But it s probably easier to remember it as the u shaped curved line created when a quadratic is graphed. Finding the range of a quadratic function may be a bit more tricky than finding the domain of a quadratic function.
Domain and range of a parabola. It fits several other superficially different mathematical descriptions which can all be proved to define exactly the same curves. Here x is the independent variable.
One important feature of the graph is that it has an extreme point called the vertex. Any point on a parabola is at an equal distance from. One description of a parabola involves a point the focus and a line the directrix.
Domain of a parabola or domain of a quadratic function would just be the set of values for which the function exists and is valid. A special curve shaped like an arch. Sometimes you can use a graphing calculator to possess an accurate picture of the function.
Define the domain and range of a quadratic function by identifying the vertex as a maximum or minimum. 2 domain and range of a parabola. A fixed point the focus and.
