Graph Quadratic Function Using Transformations

Let us first look specifically at the basic monic quadratic equation for a parabola with vertex at the origin 00. Where a b and c are all real numbers and a 0.

0 a x 2 b x c.

Graph quadratic function using transformations. Because the vertex appears in the standard form of the quadratic function this form is also known as the vertex form of a quadratic function. Graph quadratic function of the form f xax2 bxc steps for graphing quadratic functions using transformations 1. Whose graph will be a parabola.

A quadratic equation is a polynomial equation of degree 2. Using transformations to graph quadratic functions continued 5 1 use the graph of f x x 2 as a guide to graph transformations of quadratic functions. Horizontal and vertical translations change the vertex of f x x 2.

If we replace 0 with y then we get a quadratic function. 5 1 using transformations to graph quadratic functions 319 example 5 automotive application the minimum braking distance d in feet for a vehicle on dry concrete is approximated by the function d v 0045 v 2 wher e v is the vehicles speed in miles per hour. Graph quadratic functions using transformations we have learned how the constants a h and k in the functions f x x 2 k f x x h 2 and f x a x 2.

Where h k is the vertex of f x ax2 bxc and x h is the axis of symmetry. The standard form of a quadratic equation is. Parent function transformation f x x 2 g x h x h 0 2 k vertex.

Y a x 2 b x c. Write the function f x ax2 bxc as f xaxh2 k by completing the square in x. The graph of f x x 2 is shifted.

The standard form is useful for determining how the graph is transformed from the graph of latexyx2latex. In particular we will use our familiarity with quadratic equations. With a0 where we will be concerned with three general types of transformations in the variables x and y.

The figure below is the graph of this basic function. Graphing quadratic equations using transformations. H k the vertex of g x x 4 2 2 is 4 2.
