write functions for each of the following transformations using function notation. Choose a different letter to represent each function. For example, you can use art represent rotations. Assume that a positive rotation occurs in the counterclockwise direction. Translate are youa units to the right in the units of reflection across the Y axis reflection across the X axis rotation of 90° counterclockwise about the origin .0 rotation of 180° counterclockwise about the origin .0 rotation 270° counterclockwise about the origin .0
