Your answer would be 4 over x to the sixth which would look like this
4
_
x^6
the ^ symbol means it’s an exponent
        
             
        
        
        
we are given 

part-A:
Since, x is number of tablets
C(x) is cost of producing x tablets
so, vertical box is C(x)
so, we write in vertical box is "cost of producing x tablets"
Horizontal box is x
so, we write in horizontal box is "number of tablets"
part-B:
we have to find average on [a,b]
we can use formula 

we are given point as
a: (15 , 395)
a=15 and C(15)=395
b: (20, 480)
b=20 , C(20)=480
now, we can plug values

...........Answer
part-c:
we have to find average on [b,c]
we can use formula 

we are given point as
b: (20, 480)
b=20 , C(20)=480
c:(25,575)
c=25 , C(c)=575
now, we can plug values

I cannot see the images, but... 
y = | x | + 5 
consider the absolute value function. You know that for every value of x, y will be greater than or equal to 5.  this means that the y-intercept will also be the bottom of the curve. 
Plug a few values in for an idea of what the graph will look like: 
f(-1) = 6    (-1,6)
f(1) = 6     (1, 6)
f(-2) = 7    (-2, 7)
f(2) = 7     (2, 7)
The graph will have a minimum value at (0,5), where two lines will converge. The graph will look like a pointy cone with its point at (0,5), with two lines pointing outward and upward from this point. Confirm that the graph passes through the coordinates provided above! 
        
             
        
        
        
Answer:
A -2*-2 ≠- 4 
Step-by-step explanation:
sqrt(-4)
The answer is an imaginary number
-2*-2 = 4 not -4
