Using a graphing calculator, we can see the graph of the function y = x²-4x+1:
as we can see, the vertex of the function is (2,-3), and the solutions are (0.3,0) and (3.7,0)
 
        
             
        
        
        
Answer:
Domain : All real numbers
Range: y >= 0
Step-by-step explanation:
 
        
                    
             
        
        
        
The y intercept and -4 and going down 2 and 1 right u til you reach the end of the graph
        
             
        
        
        
5/7
6*5/6*7
30/42
30/42 = 30/42
Yes, 5/7 and 30/42 form a proportion.
