In 2010, the average cost of electricity was 11.54 cents per kilowatt hour. In 2014, the average cost of electricity was 12.52 cents per kilowatt hour.
Which function models the average retail price of electricity, f(x), in cents per kilowatt hour, x years after 2010?
f() = 0.98x + 4.00
f(x) = 0.245x + 11.54
f(x) = 0.738x + 11.54
f(x) = 4.082x + 1962.89
