# Show given function is a good estimate and make prediction

The principal at Park High School records the total number of students each year. The table below shows the number of students for each of the last 8 years.

Create a scatter plot showing the relationship between the year and the total number of students.

Show that the function $y = 600(1.05)^x$ 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?

1. Plot each point on the coordinate plane.
2. Graph $y = 600(1.05)^x$ on the coordinate plane.
3. Compare the graph of the function to the scatter plot of the data.
4. Use the function to estimate the population in year 9.
