OG详解-OG4 数学2 Q7

The correct answer is 50. It’s given that the function f gives the total number of people on a company retreat with x managers. It’s also given that 7 managers are on the company retreat. Substituting 7 for x in the given function yields f (7)= 7(7)+1, or f (7)= 50. Therefore, there are a total of 50 people on a company retreat with 7 managers.
