Create a scatter plot showing the relationship between the year and the total number of students. Show that the function is a good estimate for the relationship between the year and the population. Approximately how many students will attend the high school in year 9?

- Plot each point on the coordinate plane.
- Graph
on the coordinate plane. - Compare the graph of the function to the scatter plot of the data.
- Use the function to estimate the population in year 9.
