A change to the inside of the function notation is always a left/right or horizontal change to the graph.

Answer: A

Subtracting 5 actually shifts the graph to the right by 5 units. It's counter-intuitive and there are many ways to explain why it's the opposite of what you think it'd do, but it is a shift to the right by 5 units.

A change outside the f(x) notation is an up/down or vertical change to the graph.

In the figure below, WU ≅ VT.

The congruency theorem gives you an opportunity to prove that two triangles are congruent.

Consider triangles WUT and VTU. In these triangles:

WU≅VT (given);
∠T≅∠U, m∠T=m∠U=90° (from the diagram);
side TU is common.

Note that triangles WUT and VTU are right triangles, because m∠T=m∠U=90°. Side TU is common leg and sides WU and VT are hypotenuses.

HL theorem states: if the hypotenuse (WU) and one leg (TU) of a right triangle (ΔWUT) are congruent to the hypotenuse (VT) and one leg (TU) of another right triangle (ΔVTU), then the triangles are congruent.
