Vertical Translation Example:

First STEP

  • Find the Y =
  • Clear out an data in Y1, Y2, Y3, etc.


<<<<<<<<------------------------------------------------------------

This what your screen should look like before you begin!

Where y = is located on the calculator!

Second Step

Let's insert the following equations into y = so they are on the same graph:


  • y = x^2
  • Y1
  • (arrow down)

  • y = x^2 + 2
  • Y2
  • (arrow down)

  • y = x^2 - 2
  • Y3
  • GRAPH

Does your graph match the graph below?

Horizontal Translation Example:

First Step

  • Find the Y =
  • Clear out an data in Y1, Y2, Y3, etc.

Second Step

Let's insert the following equations into y = so they are on the same graph:


  • y = 2^(x + 5)
  • (arrow down)
  • Y1

  • y = 2^x
  • (arrow down)
  • Y2

  • y = 2^(x -.5)
  • Y3
  • GRAPH

Does your graph match the graph below?

Don't forget!!!

Horizontal Translation:


You move in the opposite direction of the what sign is in the equation


+ = move left - = move right
