Q: How do we solve composition of transformation problems?:


A: To do a composition of transformations problem correctly 
First ,you must do the second transformation first and then the first  transformation second. (shown in figure1)

Figure 1

In this case you would do the translation(3 ,4) first then the reflection R x-axis second

        NOW YOU TRY :

Given triangle ABC:

A(1,4), B(3,7), C(5,1)

Graph and label the following composition:
