Which situation best describes the transformation between f(x) = 10x and g(x) = –2 · 10x?

the graph of g(x) = –2 · 10x is transcribed 2 units to the right.
the graph of g(x) = –2 · 10x is transcribed 2 units to the left.
the graph of g(x) = –2 · 10x is compressed vertically and reflected across the x-axis.
the graph of g(x) = –2 · 10x is stretched vertically and reflected across the x-axis.
