Answer:
Please check the explanation.
Step-by-step explanation:
Finding Domain:
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
From the given graph, it is clear that the starting x-value of the line is x=-2, the closed circle at the starting value of x= -2 means the x-value x=-2 is included. 
And the line ends at the x-value x=1 with a closed circle, meaning the ending value of x=1 is also included.
Thus, the domain is:
D: {-2, -1, 0, 1}       or    D: −2 ≤ x ≤ 1
Finding Range:
We also know that the range of a function is the set of values of the dependent variable for which a function is defined
From the given graph, it is clear that the starting y-value of the line is y=0, the closed circle at the starting value of y = 0 means the y-value y=0 is included. 
And the line ends at the y-value y=2 with a closed circle, meaning the ending value of y=2 is also included.
Thus, the range is:
R: {0, 1, 2}   or    R: 0 ≤ y ≤ 2

Answer:
216m^3
Step-by-step explanation:
find the area of the face 12m
times the face by the length 
18×12=216
 
        
                    
             
        
        
        
X is the amount of weeks.
Equation: 425+25x=875-15x
Solve for x:
25x+15x=875-425
40x=450
x=11.25
The answer is 11.25 weeks.
