Feb 19, 2024 · Identify and label the vertex, axis of symmetry, focus, directrix, and endpoints of the latus rectum. Answer. Start by writing the equation of the parabola in standard form. The standard form that applies to the given equation is (x − h) 2 = 4 p (y − k). (x − h) 2 = 4 p (y − k). Thus, the axis of symmetry is parallel to the y-axis.
Oct 8, 2024 · This is the equation of the axis of symmetry for parabolas in the standard form y = ax 2 + bx + c. Similarly, if the parabola opens horizontally (i.e., left/right), we can get the equation for the axis of symmetry by finding the midpoint of the y-intercepts. Finding the Axis of Symmetry of the Parabola y = 2x2 + 8x + 5.
Oct 6, 2021 · A parabola is the set of all points (x, y) (x, y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0, 0) (0, 0) and the x -axis as its axis of symmetry can be used to graph the parabola.
(b) When p<0p<0 and the axis of symmetry is the x-axis, the parabola opens left. (c) When p>0p>0 and the axis of symmetry is the y-axis, the parabola opens up. (d) When p<0p<0 and the axis of symmetry is the y-axis, the parabola opens down. The key features of a parabola are its vertex, axis of symmetry, focus, directrix, and latus rectum.
The axis of symmetry is the line that splits the parabola into two equal halves. If the parabola is vertical, then the axis of symmetry passes through the vertex and is the vertical line x = h. If the parabola is sideways, then the axis of symmetry passes through the vertex and is the horizontal line y = k.
A parabola is formed by the set of all points that are equidistant from the focus and directrix. Note that the focus is always inside of the parabola and on the axis of symmetry. A parabola opens in the direction of the focus. Also, the direction in which a parabola opens never changes.

Aug 3, 2023 · The vertex form of a quadratic equation is y = a (x – h) 2 + k, Equation of axis of symmetry is, x = h, here (h, k) = vertex of the parabola. We obtain the vertex of the function (x, y) by substituting the value of x in the standard form of the equation and get the value of y. Let us solve some examples involving the above formulas and concepts.
