Answer:
I believe it would be the last table. 
Step-by-step explanation:
A linear function has an equation of y=Mx+b where y and x are the variables but m (the slope) and b are constants. The slope for the last table is -8 as the y values are decreasing by 8 every time you move forward one in the x axis. None of the other tables have a constant slope which means they don’t have straight lines when you graph them. Therefore, the last table would have to be the only one representing a linear function 
 
        
             
        
        
        
Answer:
The person is 14 years old
Step-by-step explanation:
1. Multiply 6 times 18 which is 108
2. Add all numbers together in list which is 94
3. Subtract 94 from 108 which is 14
4. To check answer add 94 plus 14 and divide by 6 and you will get the median which is 18, now you know this answer is correct.
 
        
             
        
        
        
4 times 4 which is 8 so 8 times 4 which is 32 so divide that by 138 but divide the 138 first and you will get 17.25?
        
             
        
        
        
Answer:
Absolute minimum = 1.414
Absolute maximum = 2.828
Step-by-step explanation:

For absolute minimum we take the minimum values of  and
 and  .
.

Plugging in the minimum values in the function. 

Absolute minimum value will be always positive.
∴ Absolute minimum = 1.414
For absolute maximum we take the maximum values of  and
 and  .
.

Plugging in the maximum values in the function. 

Absolute maximum value will be always positive.
∴ Absolute maximum = 2.828
