Answer:
f(1) = 2
f(n) = 2 × f(n - 1) , n ≥ 2
Step-by-step explanation:
the point of coordinates (1 , 2) is on the graph 
Then
f(1) = 2
…………………………
We notice that :
f(2) = 4
f(3) = 8
f(4) = 16
16/8 = 8/4 = 4/2 = 2/1 = 2
________________________
This means the common ratio 
of the geo sequence = 2
Hence ,
f(n) = 2 × f(n - 1) 
 
        
             
        
        
        
Answer:
Step-by-step explanation:
<u>The area of the tabletop:</u>
- A = πr² = πd²/4 = 3.14*4²/4 = 12.56 ft²
 
        
                    
             
        
        
        
2 lines intersect at (1,2) 
so answer is Yes. 
(1,2) is the solution to the system.
