intervals of increase/decrease

Front

What is an interval of increase?

Back

An interval of increase is a range of x-values where the function's output (y-values) is rising as x increases.

Front

What is an interval of decrease?

Back

An interval of decrease is a range of x-values where the function's output (y-values) is falling as x increases.

Front

How do you determine intervals of increase or decrease from a graph?

Back

Look for sections of the graph where the slope is positive (increasing) or negative (decreasing).

Front

What does the domain of a function represent?

Back

The domain of a function represents all possible input values (x-values) for which the function is defined.
