In this lesson, you learned how to:

• Graph a quadratic data set using technology.
• Find a regression curve, or curve of best fit, using a quadratic data set.
• Use a regression curve to create a quadratic model for making predictions.
• Make predictions about a real-world situation using a quadratic data set.

Here are the activities that helped you reach those goals:

• 8.12.1: Graphing a Quadratic Data Set Using Technology
  • In this activity, you learned how to represent a data set using Desmos. You looked for a visual pattern in a sample data set.
• 8.12.2: Finding the Curve of Best Fit
  • In this activity, you used graphing technology to generate a curve of best fit when given a data set.
  • 8.12.2: Self Check
  • 8.12.2: Additional Resources
• 8.12.3: Making Predictions Using a Quadratic Model
  • In this activity, you found a curve of best fit from a data set that you used to make predictions about a real-world situation.
  • 8.12.3: Self Check
  • 8.12.3: Additional Resources
• 8.12.4: Finding the Missing Data in the Set
  • In this activity, you populated a sample data set from a curve of best fit.

After these activities, you completed the following practice:
