Identify the operation that will transform the graph of f x 4 into the graph of g x 2 4 O g x cannot be obtained by any of these tranforms g x is obtained by reflecting fix in the y axis then shifting upward 2 units g x is obtained by reflecting f x in the x axis then shifting upward 2 units O g x is obtained by reflecting f x in the x axis then shifting downward 2 units O g x is obtained by reflecting f x in the y axis then shifting downward 2 units
