Set

Based on each of the given representations of a function, determine the following.

  1. Is it linear, exponential or neither? (If neither, do not do parts b-d.)

  2. If the function is linear or exponential, state whether it is discrete or continuous.

  3. Identify the rate of change as a slope (common difference) or a growth factor (common ratio).
