1st project Project Point 9 (both)

9. a function must have been defined before it is called in an expression Is this saying that if we call a function like printsum(x,y) that the printsum function is defined before it is called Or is the dotpoint saying that if you call printsum there HAS to be a function called printsum that exists (i.e. you cant just call a random function that hasnt been declared)

Possibly, but it is a bit ambiguous you could probably have an assumption in your assumption doc about it.

This definitely has to be true. I believe the point 9 is stating that in the ml file the function definition has to come before the function call. However, you can assume otherwise since it is a bit ambiguous.
