(a) Using a graphing utility, graph the two functions y= x + 2 and y = x² in the viewing rectangle [0, 4, 1] x [0, 16, 2]. If your graphing utility allows, include the y-axis gridlines in the picture; they'll be helpful in part (b). (b) Suppose that we use the two functions in part (a) as the given functions in Example 7. On the basis of the graph in part (a), make a rough estimate for the minimum length of the road. (c) Use the technique of Example 7 to find the exact value for the minimum length.
