In a particular​ city, taxicabs charge passengers ​$3.70 for entering a cab and then ​$0.40 for each​ one-fifth of a mile​ (or fraction​ thereof) traveled. If x represents the distance traveled in​ miles, then​ C(x) is the cost of the taxi​ fare, where ​C(x)equals​$3.70 if xequals​0, ​C(x)equals​$4.10 if 0less thanxless than or equals​0.2, and so on. The graph of C is shown to the right. Use the graph to find each of the following​ limits, if it exists.
