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 occurs in the counterclockwise
direction.
• translation of a units to the right and b units up
• reflection across the y-axis
• reflection across the x-axis
• rotation of 90 degrees counterclockwise about the origin, point o
• rotation of 180 degrees counterclockwise about the origin, point o
• rotation of 270 degrees counterclockwise about the origin, point o
