I can rewrite quadratic equations from standard to vertex and vice. It is also called an "Equation of Degree 2" (because of the "2" on the x) 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. Step 3: Plot the vertex and the axis of symmetry. Working with quadratic functions can be less complex than working with higher degree functions, so they provide a good opportunity for a detailed study of function behavior.

Quadratic Equations. – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 67d0d2-YzU3Z 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. Properties of Quadratic Functions f(x) = ax2 + bx + c, a > 0 f(x) = ax2 + bx + c, a < 0 y x y minimum decreasing increasing x = − b 2a x maximum increasing decreasing x = − b 2a Because the vertex is the highest or lowest point on a parabola, its y-coordinate is the maximum value or minimum value of the function. Step 1: Identify a, b, and c. Step 2: Find the vertex. Characteristics of Quadratic functions f(x)= ax2 + bx + c f(x) = a (x h)2 + k Vocabulary Parabola: The ____ shaped graph of a quadratic function. The vertex of a parabola lies on the Learn more Example 2: Graph =32−6+1. Recognizing Characteristics of Parabolas . Free quadratic equation calculator - Solve quadratic equations using factoring, complete the square and the quadratic formula step-by-step. The graph of a quadratic function is a U-shaped curve called a parabola. Key Characteristics of Quadratic Functions MGSE9-12.F.IF.4 Using tables, graphs, and verbal descriptions, interpret the key characteristics of a function which models the relationship between two quantities. The name Quadratic comes from "quad" meaning square, because the variable gets squared (like x 2). Parabola is the graph of a quadratic function. F x 2 x 3 2 4. Step 5: For extra accuracy… Find another point to … Sketch a graph showing key features including: intercepts; interval where the function is increasing, decreasing, positive, or negative; Characteristics of Parabolas. Quickly master how to find characteristics of quadratic functions. Step 4: Plot the y-intercept and its reflection in the axis of symmetry. Graphing a Quadratic Function in Standard Form. Share – 5-10 minute class discussion of ideas answering the prompt “Describe different characteristics of quadratic functions and their graphs” Part of the reason for setting up this subsection in the way I did was to provide opportunities for students to engage in the four major domains of language (listening, reading, speaking and writing). X intercepts are the x values where the parabola intersects the x axis. An x-intercept of a graph is the x-coordinate of a point where the graph The graph of a quadratic function is a U-shaped curve called a parabola.

Characteristics of quadratic functions find the zeros of each quadratic function from its graph. Section 2.2 Characteristics of Quadratic Functions 73 Graphing Quadratic Functions Using x-Intercepts When the graph of a quadratic function has at least one x-intercept, the function can be REMEMBER written in intercept form, f(x) = a(x − p)(x − q), where a ≠ 0.
