600km??? Because it’s travelling 600km and hour so it’s average is 600km and hour
        
             
        
        
        
Check the graph and observe where x = 2.
And check where it cuts across the line of the graph.
If you trace the graph carefully, when x = 2, y = -2
So the value of the function is -2.   
I hope this helps.
