growth of margo’s tree

month	height of tree (ft)
3	1.5
5	2.1
7	2.7
9	3.0
11	1.8

which statement can be supported by the information in the table?

• the tree increased in height each month during the entire 11-month period.
• the tree decreased in height each month during the entire 11-month period.
• the tree increased in height each month until the time period between month 9 and month 11.
• the tree decreased in height each month until the time period between month 9 and month 11.

Explanation:

Check height changes: Month 1 (1.4) → 3 (1.5, increase), 3→5 (2.1, increase), 5→7 (2.7, increase), 7→9 (3.0, increase), 9→11 (1.8, decrease). So it increased until month 9 - 11, then decreased.

Answer:

The tree increased in height each month until the time period between month 9 and month 11.
