Problem
(18) Which sequence of transformations was most likely applied to figure \( Q R S T U \) to form \( Q^{\prime} R^{\prime} S^{\prime} T^{\prime} U^{\prime} \) as shown below? Reflection across the \( x \)-axis, translation 3 units left. (B) Reflection across the \( x \)-axis, translation 3 units right. (C) Reflection across the \( y \)-axis, translation 4 units up. (D) Reflection across the \( y \)-axis, translation 4 units down.
Solution
Step 1 ：Identify reflection across $x$-axis or $y$-axis.
Step 2 ：Verify transformation with specified translation.
