Master How to determine the intervals that a function is increasing, decreasing or constant

The video tutorial explains how to determine the intervals where a graph is increasing, decreasing, or constant. It emphasizes reading graphs from left to right and using X values to write intervals. The tutorial provides examples of different graph behaviors, including exponential and decay functions, and explains how to identify and write intervals for these behaviors. The video concludes with a summary of the key points discussed.

• Y-axis

• Z-axis

• W-axis

• X-axis

When writing intervals for a graph, which direction should you read the graph?

• Right to left

• Left to right

• Top to bottom

• Bottom to top

What type of function is described as having a graph that decreases and then appears constant?

• Linear function

• Quadratic function

• Exponential decay function

• Logarithmic function

How do you denote an interval that does not include its endpoint?

• Using curly braces

• Using parentheses

• Using brackets

• Using square brackets

What does a straight line on a graph typically represent?

• Constant interval

• Decreasing interval

• Undefined interval

• Increasing interval

Which symbol is used to indicate that a point is included in an interval?

• Parentheses

• Brackets

• Curly braces

• Angle brackets

What is the behavior of a graph from negative infinity to positive infinity in the last example?

• Oscillating
