Let's analyze the options:
a. The rate of change is 4: This statement suggests the plant grows 4 centimeters every week. We need to check if this matches the graph.
b. The rate of change is 1: This statement implies the plant grows 1 centimeter every week. We need to verify this from the graph.
c. The rate of change is 1/4: This statement suggests the plant grows 1/4 of a centimeter every week. We'll see if this aligns with the graph.
d. The plant grows 4cm in 1 week: This statement corresponds to the rate of change being 4.
e. The plant grows 1cm in 4 weeks: This statement aligns with the rate of change being 1/4.
Analyzing the graph and options, the correct statements are:
b. The rate of change is 1.
e. The plant grows 1cm in 4 weeks.
