The shape of f(x) - x2, but shifted three units to the right and seven units down 48. The shape of f(x) = x2, but shifted two units to the left, nine units up, and then reflected in the x-axis 49. The shape of f(x) = x3, but shifted 13 units to the right 50. The shape of f(x) = x3, but shifted six units to the left, six units down, and then reflected in the y-axis 51. The shape of f(x) = [x], but shifted 12 units up and then reflected in the x-axis 52. The shape of f(x) = [x). but shifted four units to the left and eight units down 53. The shape of f(x) = _x, but shifted six units to the left and then reflected in both the x-axis and the y-axis 54. The shape of f(x) = /x, but shifted nine units down and then reflected in both the x-axis and the y-axis
