Back

By analyzing the slope of the graph; positive slope indicates increasing, negative slope indicates decreasing.

What is the significance of the maximum value of a function?

Back

It represents the highest point on the graph, indicating the greatest output value.

Front

What is the significance of the minimum value of a function?

Back

It represents the lowest point on the graph, indicating the least output value.

Front

How do you express an interval in interval notation?

Back

Use parentheses for open intervals and brackets for closed intervals, e.g., (a, b) or [a, b].

Front

What does the notation (-∞, -1) U (1, ∞) represent?

Back

It represents the union of two intervals: all values less than -1 and all values greater than 1.
