2. Describe in words how the money in the account is changing week by week.
3. Use technology to create a graph of each function. How can you see your description in each graph?

Consider the same five functions:

1. For each of the following descriptions, choose a different function from the given list and change it so it matches the description.
   1. starts with a balance of \$300 and loses \$40 each week
   2. starts with a balance of \$500 and gains \$15 each week
   3. starts with a balance of \$500 and loses of its value each week
   4. starts with a balance of \$700 and gains of its value each week
2. Here are four graphs. For each of your new equations, choose a graph that matches it. Explain your reasoning.
