Big Ideas: The unit rate of a linear function is always constant. Unit rates calculated between consecutive intervals of equal length in an exponential function change by a constant factor. This lesson plan uses the same job pay scenario that was used in lessons 1-3. Students are asked to make a table of values and a graph for the two job pay options, and then find their unit rates. Students will notice that the linear function has a constant unit rate of $50, where the exponential function has unit rates in consecutive intervals of equal length that are changing by an equal factor. Vocabulary: exponential function, linear function, unit rate of change
