Domain is x’s and range is y’s. 
For a, the domain is -2<=x<1
For a, the range is 1<=y<2
For b, the domain is 1<=x<=2
For b, the range is -2<=y<=2
(The <= is the ones with a line under, meaning equal to, if that makes sense. So write with a line under rather than equal sign)
Hope this helps!

Step-by-step explanation:
If the tickets given to employees = 40 
Then tickets given to listeners = 2 x no of employees tickets 
= 2 x40 = 80
Total tickets = 40+ 80 = 120
 
        
             
        
        
        
In this case if x<100 George will be losing money.  So he will only earn a profit when he sells more than 100 DVDs.  Essentially (x-100) represents his break-even point.
