intervals of increase or decrease

Front

What is an interval of increase?

Back

An interval of increase is a section of a graph where the function's value rises as the input value increases.

Front

What is an interval of decrease?

Back

An interval of decrease is a section of a graph where the function's value falls as the input value increases.

Front

What does it mean when a graph is constant?

Back

A graph is constant when the function's value does not change as the input value increases.

How can you identify an interval of increase on a graph?

Back

You can identify an interval of increase by looking for sections where the graph slopes upwards from left to right.

Front

How can you identify an interval of decrease on a graph?

Back

You can identify an interval of decrease by looking for sections where the graph slopes downwards from left to right.

Front

What does a horizontal line on a graph indicate?

Back

A horizontal line indicates that the function is constant over that interval.

Front

What does the slope of a line represent in a graph?

Back

The slope of a line represents the rate of change of the function; a positive slope indicates increase, while a negative slope indicates decrease.

Front

What is the significance of points A and B on a graph?

Back

Points A and B can represent specific values where the function changes from increasing to decreasing or vice versa.

Front

What does it mean if a graph has both increasing and decreasing intervals?

Back

It means that the function has varying rates of change, with some sections where the value rises and others where it falls.

Front

How do you determine the intervals of increase and decrease from a table of values?

Back

By comparing the y-values of consecutive x-values; if the y-value increases, it's an interval of increase; if it decreases, it's an interval of decrease.
