Answer: the range for one game is {$0, $2,590,000}
Explanation:
The revenue, on average, can be written as: 
Y = $35*x 
where y is the revenue and x is the number of tickets sold. 
The domain of this function is equal to {0, 74000} this means that they can sell any whole number of tickets between 0 and 74000. 
To find the range we need to evaluate y in bot extremes of the domain (because we have a linear relation) 
minimum revenue 
y(0) = $35*0 = $0 
maximum revenue 
y(74000) = $35*74000 = $2,590,000 
So the range for one game is {$0, $2,590,000}
