Dlx question in the test

i’ve seen that in past tests we have to solve a different kind of dlx question ,where we are introduced to a new function…i cant understand how to solve these questions just by looking at the solutions of previous tests, is there a video/ recitation where an example of questions like these is solved?

Aakash and I solved one question each in our last tigbur hours. The hebrew recording (of my tigbur) is now on youtube so i suggest you go watch it.
