Description |

How Does Your Garden Grow? | Students are given a linear and an exponential function, one represented verbally and the other by a table. Then students are asked to compare the rate of change in each in the context of the problem. |

Prove Linear | Students are asked to prove that a linear function grows by equal differences over equal intervals. |

Prove Exponential | Students are asked to prove that an exponential function grows by equal factors over equal intervals. |

Linear or Exponential? | Students are given four verbal descriptions of functions and asked to identify each as either linear or exponential and to justify their choices. |

Fit a Function | Students are given a set of data and are asked to use technology to create a scatter plot and write a function that fits the data set. |

Appreciation for Car Depreciation | Students will use information from the internet or a car dealership's advertisement to identify a car and determine the future value of the car using different depreciation rates over different intervals of time. Students will graph their data to show exponential decay and compare to a linear decrease on the same graph. |
