The graph of is a parabola. The graph looks like if a > 0 if a < 0 The maximum or minimum point on the graph is called the vertex. The x-coordinate of the vertex is: The y-intercept; the y-coordinate of the point where the graph intersects the y-axis. Example 1: 4x - 12x 2. Given any quadratic expression, first, check for common factors, i.e. 4x and 12x 2. We can observe that 4x is a common factor. Let’s take that common factor from the quadratic expression. 4x - 12x 2 = 4x (1 - 3x) Thus, by simplifying the quadratic expression, we get the expression, 4x - 12x 2.

Consider the graph of If , the parabola opens upward If , the parabola opens downward Axis of Symmetry (axis for short) – line of symmetry Vertex – point where the parabola intersects the axis Definition: Vertex Form of a Quadratic Function Any quadratic function , , can be written in the vertex form The graph of f is a parabola with vertex. What is a quadratic graph? A quadratic graph has an equation that involves x². Once drawn, the graph makes a smooth curve. All of the following are quadratic equations and each produce a quadratic graph: y = x² y = x² + 5x + 6 y = x² + 5 y = x² + 2x - 5 y = x² - 3x y = x² - 6x + 18 Draw the graph of y = x² for -3 ≤ x ≤ 3.

A quadratic functionis a function that can be written in the form of f x a x h )2 + k (a ≠ 0). In a quadratic function, the variable is always squared. The table shows the linear and quadratic parent functions. Notice that the graph of the parent function f(x) = x2 is a U-shaped curve called a parabola. Quadratic Equations A term like x2 is called a square in algebra because it is the area of a square with side x The adjective quadratic comes from the Latin word quadratum for square. So a quadratic equation is one in which the highest index number of a term with x in is x2 Examples of quadratic equations: y = x2 y = x2 + 1 y = x2 + 3x - 10. Transformations of Quadratic Functions Transformation A dilation is a transformation that makes the graph narrower or wider than the parent graph. A reflection flips a figure over the x-axis or y-axis. Vocabulary Dilations Example 1: Describe how the graph of d(x) = x2 is related to the graph f(x) = x2. __ 1 3 Answer: Since 0 < < 1, the graph. Curved Line Graphs Learning Objectives To recognise and plot quadratic graphs When an object is thrown into the air, its distance above the ground is given by this equation: y = -5x2 + ux (y is the distance, x is the time, u is the speed) Plot the graph of a bullet shot at 200m/s: y = -5x2 + 200x Ballistics What is the maximum height reached?. A parabola is the graph of a quadratic function, which you can write in the form y = ax2 + bx + c, where a cannot be 0. Essential Understanding. The graph of ANY quadratic function is a transformation of the graph of the parent quadratic function y = x2. Section 4.1 – Quadratic Functions and Translations. a) Solve quadratics using graphical methods. b) Sketch parabolas from quadratic equations, considering intercepts with the axis. c) Find the minimum or maximum point of a quadratic by completing the square.
