What effect would the transformation y = -2/(3z) have on the graph of y = f(=)? O horizontal compression by a factor of , then a vertical compression by a factor of O a reflection about the y-axis, a horizontal compression by a factor of _, and a vertical expansion by a factor of 2 O a reflection about the x-axis, a horizontal compression by a factor of !, and a vertical expansion by a factor of 2 O horizontal expansion by a factor of 3, then a vertical expansion by a factor of 2
