### Description

Your students practice regression modeling using constructed data, including determining the appropriate type of function. Three single-page editable Microsoft Word documents, each one "word problem" and each with constructed data and some scaffolding questions guiding students through the process. Students determine the best choice of regression model and make a prediction about a missing value or find when the function is expected to have a particular value. With my scanned (hand-written) answer keys (PDF format).

### Standards

to see state-specific standards (only available in the US).
Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).
Distinguish between situations that can be modeled with linear functions and with exponential functions.
Graph the solutions to a linear inequality in two variables as a half-plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.
Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
