It has been observed that a plant is growing over time.  When the plant arrived at the nursery, it was 2 cm tall, and it appears to be growing .5 cm per week.  You plan to watch it grow for 8 weeks before you expect it to stop. What is the independent variable in this situation?

• Time
• Height

It has been observed that a plant is growing over time.  When the plant arrived at the nursery, it was 2 cm tall, and it appears to be growing .5 cm per week.  You plan to watch it grow for 8 weeks before you expect it to stop. Make a table of this information. What is the Range?

• Time, Range:     0 ≤ y ≤ 8 weeks
• Height, Range: 2 ≤ y ≤ 6 cm
• Height, Range: .5 ≤ y ≤ 8 cm
• Height, Range: 2 ≤ y ≤ 8 cm
