Did you get (1, 6) as the coordinates of the point on the blue graph that resulted in the location of the red parabola and the black parabola in the same place on the green graph?
Let's think about those two numbers remembering to view the labels on the axes.
I'm thinking of two numbers. Their sum is 1 and their product is 6. What are the two numbers? More generally, two numbers have sum a and product b. What are the two numbers?
 CHALLENGE: Can you look at the blue graph to find the two numbers with the sum of 1 and the product of 6? What are they?
