CCSS IP Math I 4.2.3 Example 2

Lindsay created the table below showing the population of fruit flies over the last 10 weeks. She estimates that the population of fruit flies can be represented by the equation . Using residuals, determine if her representation is a good estimate.
  1. Find the estimated population at each x-value.
  2. Evaluate the equation at each value of x.
  3. Find the residuals by finding each difference between the observed population and estimated population.
  4. Create a residual plot.
  5. Analyze the residual plot to determine if the equation is a good estimate for the population.
