a Compared to the graph of y = , the graph of y =  – 4 is a vertical stretch by a factor of 3 and a translation of 4 units left.

b Compared to the graph of y = , the graph of y =  – 4 is a vertical shrink by a factor of 3 and a translation of 4 units up.

c Compared to the graph of y = , the graph of y =  – 4 is a vertical stretch by a factor of 3 and a translation of 4 units down.

d Compared to the graph of y = , the graph of y =  – 4 is a vertical shrink by a factor of 3 and a translation of 4 units down.
