Question

mm = milllimeters

1. What is the Independent Variable in this graph?
2. List the range of the Dependent Variable values.
3. Explain how to interpret the data for this graph. (What is happening to the height of a growing marigold during this week?)

Answer 1

1) The independent variable is the x axis, which represents the time that has passed since the flowers began to be observed.
2) The range of the dependent variable height, the y axis, is 5mm to 30mm in this function. The lines are connected, so the relationship contains all variables in this range.
3) The independents variable is increasing with the dependent variable, so the graph shows a direct relationship where the marigold grows as time passes.
