1) Introduction to the Parabola The graph of a quadratic function is a U-shaped curve called a parabola. The point at which the curve changes direction is called the vertex. If the parabola opens upward, then the vertex is a minimum point and its y-value is the minimum value of the function. If the parabola opens downward, then the vertex is

- [Voiceover] What I have attempted to draw here in yellow is a parabola, and as we've already seen in previous videos, a parabola can be defined as the set of all points that are equidistant to a point and a line, and the point is called the focus of the parabola, and the line is called the directrix of the parabola.

Find the coordinates of the focus, axis, the equation of the directrix and latus rectum of the parabola y2 = 16x. Solution: In this equation, y2 is there, so the coefficient of x is positive so the parabola opens to the right. Comparing with the given equation y2 = 4ax, we find that a = 4.

Focus of a Parabola. The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve.. A parabola is defined as follows: For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix.

The latus rectum of a parabola is the chord that passes through the focus and is perpendicular to the axis of the parabola. LSL’ Latus Ractum = 2 (4 a. a) 2\left( \sqrt{4a.a} \right) 2 (4 a. a ) = 4a (length of latus Rectum) Note: – Two parabola are said to be equal if their latus rectum are equal. Parametric co-ordinates of Parabola

If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph.

The vertex of any parabola has an x-value equal to − b 2 a. After finding the x-value of the vertex, substitute it into the original equation to find the corresponding y-value. This y-value is a maximum if the parabola opens downward, and it is a minimum if the parabola opens upward. We can easily identify that the parabola is opening left or right. Since the coefficient in front of the x term is positive, we can say that the parabola will open to the right. The focus will be to the right of the vertex, and the directrix will be a vertical line that is the same distance to the left of the vertex that the focus is to the right. In Exercises 37–40, write an equation of the parabola shown. (See Example 4.) 37. 39. In Exercises 41–46, identify the vertex, focus, directrix, and axis of symmetry of the parabola.
