You should back it up with work showing the steps and supporting your reasoning, but yes, you should draw a 4-to-1 mux that implements f=Σ(2,5).

Also:
"Implement f=Σ(2,5) with a 4-to-1 multiplexer. am i suppose just draw the logic digram to implement the function ?"

Haha, a slipped autocorrect...

It's when the steps of reasoning rain down according to training.

I kinda like training raining steps -- has a ring to it. I wonder if I can make that into a saying that others would pick up.
