a. 

The fundamental algebraic idea (content) in this video is the notion of inverse function as reversing processes and using inverse operations.

b. 

The teacher expects students to write a function rule to start, with a relationship shown as an equation, and then backtrack to find a rule for the inverse function.

c. 

Students demonstrate their knowledge of the intended content by drawing a flow chart for a multi-step function, drawing the backtracking flow chart, and then writing an inverse function.
