Question

A plant is 2 inches tall. In sunlight, the plant grows 1 inch each week. At the end of the 4th week, the plant is placed in a dark room for 2 weeks and stops growing. It is then returned to the sunlight and grows at the same rate for the next 3 weeks. Describe how you would go about sketching the graph of this relationship. Include key features of the graph in your description.

Answer 1

Answer:

The initial height of the plant is 2 inches, so the y-intercept is (0, 2). The plant gets taller at a constant rate through week 4 and again in weeks 7–9, so the graph is linear and increases over those intervals with a slope of 1. The graph is constant on (4, 6). The plant is tallest after 9 weeks. The maximum is (9, 9).

Answer 2

I would label the x-axis with a scale 1-10 weeks and the y-axis with inches grown. The graph starts at 2inches because it’s the height of the plant. For the next 4 weeks there will be a growth of 1 inch a week (reaching 6) than the line stays at the height for 2 weeks until it gets sunlight again for 3 more weeks making it grown 3 more inches and repeats the process again.
