What is the average rate of change?

Back

The average rate of change of a function over an interval is the change in the function's value divided by the change in the input value, often represented as the slope of the line connecting two points on the graph.

What is a minimum point in a graph?

Back

A minimum point is the lowest point on a graph, where the function changes from decreasing to increasing.

Front

What does it mean if two functions are equal at a certain point, such as n(1960) = r(1960)?

Back

It means that the populations predicted by both functions are the same at the year 1960.
