y = – 3f(2x) – 1
(y + 1) / 3 = – f(2x)
Replacing x by 2x compresses the graph horizontally by a factor of 2.
Multiplying the x term by -1 reflects the graph in the x axis.
Dividing the y term by 3 elongates the graph vertically by a factor of 3.
Replacing y by y + 1 moves the graph 1 unit vertically downwards.
