The population of a certain country was approximately 50 million in 1900, 225 million in 1950, and 375 million in 2000. Construct a model for this data by finding a quadratic equation whose graph passes through the points (0,50), (50,225), and (100,375). Use this model to estimate the population in 2050. a. Let x be the number of years since 1900 and y be the population in millions b. According to the model, what will be the population in 2050
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
