5. Objective: To write a function rule that describes a relationship between two quantities.

6. We’ve explored iterate functions and written them in Now-Next form. Now let’s generate real world data and find the equations to represent that data. EX: Write the equation for the data above: Next = Now – 6; Start at 42

7.  Explore the Sequence ActivitySequence Activity  Record your results for the first 5 terms.  Write a Now-Next equation for each sequence.  Answer the following questions:

8. Write a summary of what you noticed about using different types of starting numbers, add-ons, and multipliers. The questions below may help you organize your thoughts. Starting Numbers: What effect does a negative starting number have on the sequence? What effect does a positive starting number have on the sequence?

9. Add-ons: What effect does a negative add-on have on the sequence? What effect does a positive add-on have on the sequence?

10. Multipliers: What effect does a positive multiplier have on the sequence? What effect does a negative multiplier have on the sequence? What effect does a decimal multiplier have on the sequence? What effect does a large multiplier have on the sequence?

11. What combinations of starting numbers, add-ons, and/or multipliers made the sequence increasing? What combinations of starting numbers, add-ons, and/or multipliers made the sequence decreasing? What combinations produced a linear graph? What combinations produced a non-linear graph?
