How do I do this, I have to write a function for each series of transformations *rotation of 90 degrees counterclockwise about the origin, point O, then a reflection across the x-axis
*reflection across the y-axis, then a translation a units to the right and b units up
*translation a units to the right and b units up, then a rotation of 180 degrees counterclockwise about the origin, then a reflection across the y-axis
