The continuously growing number of cellular subscribers means that the number of cell phone antennas needs to be constantly increased to carry the additional cellular traffic. The number of cell phone antennas (in thousands) located in the United States can be modeled by 0.3x2 + 12x + 118, where x stands for the number of years since 2000. If cellular services continue to grow at this rate, how many cell phone antennas should we expect in the United States in the year 2020?
