Answer:
A
Step-by-step explanation:
A function composition is where one function is substituted within another function and is written g(f(x)). Here we will substitute f(x) into g(x). For g(f(-7)), we substitute -7 for x.

Now substitute -7 for x.

Note that reflecting triangle ABC with respect to the x-axis, and translating it 3 units down, mapps it perfectly to A'B'C'.
Thus, the answer is: <span>△ABC is congruent to △A′B′C′ because you can map
</span>
△ABC to △A′B′C′ using a reflection across the x-axis followed by a translation 3 units down, which is a sequence of rigid motions.
