I think this is what it would be.
        
             
        
        
        
That is the exact representation of the constant π.  By definition:
π=C/d, where C is the circumference of a circle and d is the diameter.
        
             
        
        
        
The solution is when the two functions meet x=2. The green function is f(x), and the red is g(x).
 
        
        
        
I think it’s b I hope I’m sosososososos sorry if it ain’t
