Figure BCDE was transformed using the composition rx-axis ◦ T2,2. If point B on the pre-image lies at (3, 4), what are the coordinates of B'' on the final image?

Apply the composition from right to left. First, translate B by (2, 2): (3 + 2, 4 + 2) = (5, 6). Then reflect across the x-axis, which changes the sign of the y-coordinate, giving B'' = (5, –6), choice B.
