6.3.6 Please help me with this math problem. I am only looking for a final answer. If there are too many steps, please just provide me with the final answer. Thank you (See image)

8 4. Suppose these two pulses overlap in a medium. Note that this is a snapshot graph with x on the horizontal axis. 4 a. Fill in the table with the total displacement yr at x=0,1,...,8. (I've filled in a few.) 3 b. In the next column, write a C if there is destructive, and N if neither. constructive interference going on, D if graph below. c.
