Population of Bismarck, ND  X represents the number of years since  For example, to represent the year 2005, X = 5  Y represents the actual population in thousands.  So if the population is 57,800, Y = 57.8  X represents the number of years since  For example, to represent the year 2005, X = 5  Y represents the actual population in thousands.  So if the population is 57,800, Y = 57.8 I am going to set up a graph where:

Population Data Table Year Since 1990Population in Thousands Resource: ty/bismarck-north-dakota

Scatterplot of Data Population of Bismarck, ND

Linear Model: y =.71x The increasing population of Bismarck, ND can be modeled by the following function, where x represents the number of years after 2000 and f(x) represents the population in thousands. f(x) =.71x the term linear function refers to two different, although related, notions

I will now use my model to predict the population of Bismarck in Since the year 2014 is 14 years after 2000, I will plug 14 in for x. f(14) =.71(14) f(14) = f(14) = 64.7 (in thousands) According to my model, in 2014 the population of Bismarck will be about 64.7 thousand, or 64,700.
