What do you mean by functional requirements in context to business analyst?

Functional requirements are what the business users expect the software to 'do'; what tasks they wish it to perform. (e.g. write paychecks, calculate launch date for lunar orbit, do hours to gross calculation for movie studios, etc.)

UML says a func req is what an actor wants from a system. (An actor in UML is anyone who interacts with a system.)

McDonald's wants their system to allow a cashier to enter the order and the cooks in the back see the order's elements that they need to deliver to fill the order and complete the task.

Entering at the register and displaying at the register and the kitchen is a functional requirement of the system. Calculating the standard deviation of the poisson distributed customer arrivals is not. They do that over at Burger King.
