What is the vertical shift of the graph of the parent cosecant function to the graph of the function below? on a coordinate plane, the x-axis ranges from negative 2 pi to 2 pi with an interval of pi units and the y-axis ranges from negative 8 to 2 with an interval of 2 units. the graph is 2 pi periodic with asymptotes at x equals plus or minus n pi. it touches the lines y equals negative 2 at (0 comma negative 2) and (2 pi comma negative 2) and y equals negative 4 at (pi comma negative 4) and (negative pi comma negative 4). 1 unit down 2 units down 3 units down 4 units down
