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:
