Your Answer for Question 1:
According to the reading, if we make a truth table for this arbitrary function, we'd have one product term for each "row" (possible combination of input) that produces a 1 in the output.  Thus, if we had a function that always produces 1 for its output, regardless of its inputs, then we'd have 2^N product terms, which is also the total possible number of different combinations of inputs.

Your Answer for Question 2:
According to the digital design handout, a bus is a "collection of wires."  According to P&H, a bus is a "collection of data lines that is treated together as a single logical signal."  The diagram in the handout illustrates this concept.

Your Answer for Question 3:
y = a.a + a.b + a.not(b) given
y = a + a.b + a.not(b) idempotent
y = a + a.(b + not(b)) distributive
y = a + a.1           inverse
y = a + a             identity
y = a                 idempotent
