The numbers C(t) of cell sites from 1985 wrough 2008 can be modeled by the function: 237,101 60) = _ 1 + 19503 0355' rhere t represents the year, with t = 5 corresponding to 1985. Source: CTlAThe Wireless Association) a. Use the model to find the numbers of cell sites in the years i. 1985 ii. 2000 iii. 2006 b. Use your calculator to graph the function and sketch the graph on your assignment. You must include the viewing window you used. c. Use your calculator to determine the year in which the number of cell sites will reach 235,000. (Put 235,000 in yz, and calculate the intersection. I want you to be able to use your calculator efficiently!!!) d. Verify your answer from part c algebraically
