Explain how to obtain the graph of the given quadratic function from the graph of f(x) = - (x + 2)2 - 8

A. Take the graph of y = x2 and shift it 2 units to the left, shift it 8 units down, vertically compress it by a factor of +3, and the graph will open upward.
B. Take the graph of y = x2 and shift it 2 units to the left, shift it 8 units down, vertically stretch it by a factor of + , and the graph will open downward.
C. Take the graph of y = x2 and shift it 2 units to the right, shift it 8 units up, vertically stretch it by a factor of + , and the graph will open upward.
D. Take the graph of y = x2 and shift it 2 units to the left, shift it 8 units down, vertically compress it by a factor of + , and the graph will open downward.
