The function z] = 5-1 has been transformed to 9(2). The graph of 9(2) = 2(5)\": may be obtained by C] vertically stretching the graph of f (2) by a factor of 10 about the xaxis and horizontally stretching by a factor of % about the yaxis. C] vertically stretching the graph of f (2) by a factor of 10 about the xaxis and horizontally stretching by a factor off; about the yaxis. C] vertically stretching the graph of f (2) by a factor of 2 about the xaxis and horizontally stretching by a factor of % about the yaxis. C] vertically stretching the graph of f (2) by a factor of 2 about the xaxis and horizontally stretching by a factor of6 about the yaxis
