The federal tax rate for heads of household is given in the graph shown to the right. Use the graph to find lim r(x), lim r(x), and lim r(x). X-8992* X-8992 X-8992 In a particular city, taxicabs charge passengers $3.30 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) = $3.30 if x = 0, C(x) = $3.70 if 0 < x0.2, 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. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. +lim C(x) = $ x-0.89 (Simplify your answer. Do not include the $ symbol in your answer.) B. The limit does not exist. Cost of taxi (in dollars) 5.7- 5.3- 4.9- 4.5- 4.1- 3.74 3.34 0 0.2 0.4 0.6 0.8 Distance traveled (in miles)
