When a function is reflected, it must be reflected over a line
The new function is: 
The equation is given as:

Maybe write it down, like how you see other math problems.
And then solve it!
:D
The answer is D. First, it is the segment addition postulate because the two segments make up the whole. Second, it's substitution because you are substituting EF + FG for FH.
Hope this helps!
