What are the 2 different types of parabolas?
Concave Up: When a parabola opens upward and the constant a is greater than 0 then it is known as concave up. Concave Down: Similarly, when the constant a is lesser than 0 then it is known as concave down. 2.
What are parabola graphs called?
The graph of a quadratic function is a U-shaped curve called a parabola. The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis.
How many types of parabolas are there?
2) When vertex as origin there are 4 types of parabola.
What are the types of graphs in statistics?
The four basic graphs used in statistics include bar, line, histogram and pie charts.
What shape is a parabola?
U-shaped
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix).
What are the parts of parabola?
- the axis (parallel to the y axis),
- the focal length , the semi-latus rectum ,
- the vertex ,
- the focus ,
- the directrix ,
- the point of the parabola intersecting the y axis has coordinates ,
- the tangent at a point on the y axis has the equation .

How to graph a parabola in a vertex form?
In case, if the parabola equation is provided in the vertex form, first check the value of a. If the value of a is positive, then the parabola graph is upwards, otherwise, it is negative. Next, determine the vertex point (h, k) from the given equation. Then, we have to substitute some value of x and find the corresponding values of y.
Which is the correct equation for a parabola?
If the X-axis and the Y-axis are interchanged, then the focus is at the point F ( 0, a), and the directrix is the line having the equation y = – a. The equation of this parabola is x 2 = 4 a y. If a > 0 the parabola opens upwards, and if a < 0 the parabola opens downwards.
What is the axis of symmetry of a parabola graph?
If the value of a is less than 0 (a<0), then the parabola graph opens downwards. The axis of symmetry from the standard form of the parabola equation is given as x= -b/2a.
How many points do you need to draw a parabola?
Two points define any line. Since parabola is a curve-shaped structure, we have to find more than two points here, to plot it. We need to determine at least five points as a medium to design a pleasing shape. In the beginning, we draw a parabola by plotting the points.
