CCHS Math 1 Unit 2a REVIEW

A particular variety of bamboo grows for 4 months out of the year at a rate of 3 inches per day. The rest of the year, the bamboo is dormant and does not grow. A graph of the growth for a 12-month period is shown. What is the domain of the function that models this phenomenon?

• 0 ≤ height ≤ 3

• 0 ≤ height ≤ 30

• 0 ≤ months ≤ 4

• 0 ≤ months ≤ 12
