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.

Find the estimated population at each x-value.

Evaluate the equation at each value of x.

Find the residuals by finding each difference between the observed population and estimated population.

Create a residual plot.

Analyze the residual plot to determine if the equation is a good estimate for the population.
