HSS.ID.B.6.a

**HSS.ID.B.6.a**: Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.

What you'll learn

Choose an appropriate model family - linear, quadratic, or exponential - from a scatter plot's form and the context
Fit a function either by using a function the context supplies or by running a regression with technology
Use a fitted function to predict values and solve contextual problems, stating answers with units
Distinguish interpolation from extrapolation and recognize when a prediction is unreliable

Review first:

Represent data on two quantitative variables with scatter plots
