Which trаnsfоrmаtiоn cоrresponds to ( y = -sqrt[3]{x + 6} + 3 )? The x-аxis spans from just below negative 5 to above zero, and the y-axis spans from below negative 5 to above 5, both with a scale of 5 in increments of 1. The blue S-shaped curve starts near the middle-left of the second quadrant with a shallow negative slope and undergoes a steep transition near x= negative 6, while passing through the point (negative 6, 3). Then it gradually continues to level out as it moves right towards the first quadrant. It extends beyond the visible portion of the graph at both ends, while crossing the y-axis at a point slightly above (0, 1). It passes through the points (negative 7, 4) and (2, 1).
