reflection across the y-axis, vertical compression by a factor of 0.1, vertical translation 4 units upB
reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units downC
vertical stretching by a factor of 0.1, vertical translation 4 units down, reflection across the y-axisD
vertical stretching by a factor of 0.1, vertical translation 4 units up, reflection across the x-axis
