Algebra 2: Transformations: Translating Functions
by Texas Instruments

Published on August 27, 2011

Objectives

  • Students will vertically translate a function by adding a constant and write the appropriate symbolic representation for the translated function
  • Students will horizontally translate a function by adding a constant and write the appropriate symbolic representation for the translated function
  • Students will identify the effect of a and b in y = f(xa) + b on the graph of a general function y = f(x)

Vocabulary

  • Transformations
  • Horizontal/vertical translations

About the Lesson

This lesson involves translating different types of function graphs using sliders. As a result, students will:

  • Understand how adding a constant outside the function moves the graph of a function up and down.
  • Discover how adding a constant inside the function moves the graph of a function left and right.
