So when you flip it, it looks like this. Write the equation for G of X. WebTo find the transformation, compare the two functions and check to see if there is a horizontal or vertical shift, reflection about the x-axis, and if there is a vertical stretch. The first step to find this new reflection equation is to interchange the variables: {eq}y=x^3 \rightarrow x=y^3 {/eq}. of everywhere you saw an x before you replaced So you may see a form such as y=a(bx-c)^2 + d. The parabola is translated (c,d) units, b reflects across y, but this just reflects it across the axis of symmetry, so it would look the same. Similar reasoning shows that, for example, $$ Yes, is a reflection in the x-axis, and yes, will shift the function up 2 units, but this doesn't mean it's a reflection in the line y=2. So you could do it like this. If {eq}f(x) = 2x^2-3x+5 {/eq} is reflected over the x-axis, then its new reflection equation is {eq}f(x) = -2x^2+3x-5 {/eq}. For an equation, first switch the variables in the equation so that x becomes y and y becomes x. To reflect the graph of y = x^2 across the x As a member, you'll also get unlimited access to over 84,000 And it does work also for the Graphing Absolute Value Functions | Translation, Reflection & Dilation, Absolute Value Inequalities | Practice Problems & Solutions, Mathematical Reflection Rules & Examples | How to Graph Reflection Over X & Y Axes, The Transitive Property of Similar Triangles, Basic Transformations of Polynomial Graphs, Writing a Polynomial Function with Given Zeros | Process, Forms & Examples, Trigonometric Functions of Real Numbers: Definition & Examples, Absolute Value Graphs & Transformations | How to Graph Absolute Value, Horizontal Asymptotes Equation & Examples | How To Find Horizontal Asymptotes, Scale Factor of a Dilation | Center of Dilation & Examples, SAT Subject Test Mathematics Level 1: Practice and Study Guide, SAT Subject Test Mathematics Level 2: Practice and Study Guide, CLEP College Algebra: Study Guide & Test Prep, NY Regents Exam - Geometry: Help and Review, High School Trigonometry: Homeschool Curriculum, High School Algebra I: Homeschool Curriculum, Holt McDougal Larson Geometry: Online Textbook Help, College Algebra Syllabus Resource & Lesson Plans, College Mathematics Syllabus Resource & Lesson Plans, NMTA Middle Grades Mathematics (203): Practice & Study Guide, Create an account to start this course today.
