I need to write a paper in sociology but I am clueless to the meaning of this

I have to write an essay, 3 to 5 pages on summarizing the analytical models of functionalism, conflict theory, and symbolic interaction. How do they view society? How do they differ? Use each model to analyze a movie you have seen. My friend told me about study pool but I don’t really know how this works? Can someone please help me?? It has to be in your own words, double spaced with 1 inch margins.
