Interpret key features of the graph of a quadratic function. . NOTES: 1. Use a graphing calculator to graph A(l) from Item 9 in Lesson 17-1. Sketch the graph on the grid. The graph of a quadratic function is a curve called a _____. A parabola has a point at which a maximum or minimum value of the function occurs. Note that the focus is always “inside” the parabola on the line of symmetry, and the directrix is “outside” the parabola. Also note that the line perpendicular to the line of symmetry (and thus parallel to the directrix) that connects the focus to the sides of the parabola is called the latus chord , latus rectum , focal width, focal ... A parabola is the set of points in a plane that are the same distance from a given point and a given line in that plane. The given point is called the focus, and the line is called the directrix. The midpoint of the perpendicular segment from the focus to the directrix is called the vertex of the parabola.

Parabolas have several recognizable features that characterize their shape and placement on the Cartesian plane. Vertex. One important feature of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. 9.3 Graphing Quadratic Equations: Sketching the graph of a quadratic function is easiest when you use a t-table. y=ax2+bx+c (a ≠0) Quadratic term is always the x2term. The shape of the graph of a quadratic function is a _____ A Parabola is a _____ figure. The line of symmetry is always through the _____. 9.2 Characteristics of Quadratic Functions Notes.notebook 1 April 01, 2014 Today's Learning Target: Students will be able to •find the zeros of a quadratic function from its graph, and •find the axis of symmetry and the vertex of the parabola. Note that in Figure 1, the parabola opens upward. In the graph below in Figure 2, notice what happens to the values of y when x is multiplied by 2 and then by 4. In comparing the graphs of y = x 2 (red), y = 2x 2 (green), and y = 4x 2 (blue), we see that each parabola opens upward but the larger the value of "a", the steeper (narrower) the graph. Projectile motion is a form of motion experienced by an object or particle (a projectile) that is projected near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible). This curved path was shown by Galileo to be a parabola. The study of such ...

Mar 06, 2014 · It wouldn't take much to do a better job than last year. Last year, I didn't even teach my students the names for the different forms of a quadratic function. We did all our graphing using the calculator last year, so I didn't think it really mattered. This year, I made it my goal that students would identify the form of a quadratic function first. Definition of a Parabola A parabola is the set of all points in a plane that are equidistant from a fixed line (the directrix) and a fixed point (the focus) that is not on the line (see Egure 13.28). Definition of a Parabola In Thapter 11, we studied parabolas, viewing them as graphs of quadratic functions in the form y = — k or y = ax2 + bx + c.

The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. Graphing Quadratics Review Worksheet Name _____ Fill in each blank using the word bank. 1. Standard form of a quadratic function is y = _____ All parabolas are vaguely “U” shaped and they will have a highest or lowest point that is called the vertex. Parabolas may open up or down and may or may not have \(x\)-intercepts and they will always have a single \(y\)-intercept. Note as well that a parabola that opens down will always open down and a parabola that opens up will always open up.

I. Quadratic Functions A. The basics The graph of a quadratic function is a parabola. A parabola for a quadratic function can open up or down, but not left or right. The vertex is either the highest or lowest point on the graph depending on whether it opens up or down. If the parabola opens down, the vertex is the highest point. y x Vertex ... If a parabola has a horizontal axis, the standard form of the equation of the parabola is this: (y - k) 2 = 4p(x - h), where p≠ 0. The vertex of this parabola is at ( h , k ) . The focus is at ( h + p , k ) . The equation of a parabola can be expressed in either standard or vertex form as shown in the picture below. The standard form of a parabola's equation is generally expressed: If a is positive then the parabola opens upwards like a regular "U". If a is negative, then the graph opens downwards like an upside down "U".
