Answer:
1st function: all negative real numbers
2nd function: all real numbers 
3rd function: all real numbers except -3 ≤ x ≤ 3
4th function: all real numbers between -3 and 3 
Step-by-step explanation:
In the picture attached, the question is shown.
The domain is the set of all the numbers that the independent variable (here, x) can assume.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
J = 50 mph by 2 hours 
S = 50 mph by 1 hour 
2-1 = 1
 
        
             
        
        
        
Let the final score of White Sox = x
the final score of Marlins = y
White Sox won by 2 runs. Thus 
x = y +2
White Sox had twice as many runs as Marlins
x = 2y
From the equations,
2y = y + 2
=> 2y - y = 2
=> y = 2
x = 2y = 2×2 = 4
Hence, final score of 
White Sox = 4
Marlins = 2
