Question

The graph represents the approximate number of bacteria in a population over time. Is the rate of change constant or varying? How do you know?

Answer 1

Varying

Explanation:

The reason why the rate of change is varying is because the dots on the graph do not connect to make a straight line when you draw a line through the dots. When the dots connect via a straight line, it is also known as a proportional relation. A straight line would be a constant change.
