11/7/2017 Unit Activity: Functions and Transformations Task 1 Functions and Transformations Transformations can be thought of as functions that take the points from one object (the pre-image) to the corresponding points on another object (the image). In the unit, you saw examples of how algebra can be used to rewrite the coordinates of points after they have been transformed. You can also use function notation to rewrite the coordinates. For example, these statements show several different ways you can use function notation for the translation, T , of a point 6 units in the positive x -direction: Part A Write functions for each of the following transformations using function notation. Choose a different letter to represent each function. For example, you can use R to represent rotations. Assume that a positive rotation
