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?
(5, 6)
(5, –6)
(1, 2)
(1, –2)

Thank you for posting your question here at . If point B on the pre-image lies at (3, 4), the are the coordinates of B'' on the final is (5, -6). Below is the solutions, I hope the answer helps. 

rx-axis ◦ T2,2 (3,4) 
= rx-axis ( T2,2 (3,4)  ) 
= rx-axis ( 5,6  ) 
= (5, -6)
