1. Describe two different situations that could be modelled by an exponential function.

2. Clearly define all variables in the relationship.

3. Interpret the growth or decay factor and the

   initial amount, which cannot be 1.

4. Explain why this type of function makes sense

   as a model for these real applications, by

   referring to key features of this function.

5. Your justification should also include reference

   to at least two of graphical, numeric, and/or algebraic models.
