I cant see the picture good can you write it out not in picture because it is blury for me I dont know about the others 
 
        
                    
             
        
        
        
Answer-
The exponential model best fits the data set.
Solution-
x = input variable = number of practice throws
y = output variable =  number of free throws
Using Excel, Linear, Quadratic and Exponential regression model were generated.
The best fit equation and co-efficient of determination R² are as follows,
Linear Regression  
Quadratic Regression
Exponential Regression
The value of co-efficient of determination R² ranges from 0 to 1, the more closer its value to 1 the better the regression model is.
Now,
Therefore, the Exponential Regression model must be followed.
 
        
             
        
        
        
To solve for the 7th term of a geometric sequence with t1 = 6 and r = 4, we use the following equation:
<span>
a(n) = a(1) r^(n-1)
a7 = (6) 4^(7-1)
a7 = 24576</span>
Hope this answers the question. Have a nice day. Feel free to ask more questions.
