Equazione della parabola con asse di
simmetria parallelo all’asse y

This summary combines slides from Melanie Tomlinson and Morrobea on the topic of parabolas. The key points covered include: - The geometric definition of a parabola as the set of all points equidistant from a fixed point (the focus) and fixed line (the directrix). - Parabolas can be represented using various equation forms including vertex form, standard form, and general form. - Methods for graphing parabolas by identifying features like the vertex, axis of symmetry, x-intercepts, focus, and directrix. - Applications of parabolas to model real-world situations like searchlights and radio telescopes.

This document discusses how to solve and graph quadratic equations. It explains that a quadratic function has the form y=ax^2 + bx + c, and that the graph of a quadratic function is a parabola. It provides steps to find the x-intercepts, y-intercept, vertex, and determine if a parabola opens up or down by analyzing the leading coefficient a. Examples are given to demonstrate how to apply these steps to solve and graph specific quadratic equations.

The document discusses parabolas and their key properties: - A parabola is defined as the set of points equidistant from a fixed point (the focus) and a fixed line (the directrix). - The vertex is the point where the axis of symmetry intersects the parabola. The focus and directrix are a fixed distance (p) from the vertex. - The latus rectum is the line segment from the focus to the parabola, perpendicular to the axis of symmetry. Its length is determined by the equation of the parabola.
