It's a question in my assignment, which I don't really understand it. However, there is an example here.
e.g. A computer uses the following logical expression to control a finger print scanner.
F(A, B, C, D) = Σ (0, 1, 4, 5, 12, 14)
What will be the truth table of the function F?
The solution looks like this:

Can anyone explain how the truth table can be drawn from the function F? Thanks
