The graph of y=2x is shown to the right. describe the transformations made to the original graph to get y=3*2 ^x-4 +2. the graph of y = 2^x the shifts units to the graph of y = 2 ^x-4 is (circle one) stretched or shrunk vertically by a factor of now, the graph of = 3*2^x-4 shifts units (circle one) up or down. given y = 3*2^x-4 + 2 when = 4, what’s the value of .
