Understanding Intervals and Graphical Representation

The video tutorial explains how to determine if given values are within specified intervals using graphical methods. It covers four different intervals: X is greater than or equal to 1, from -1 to 9, from -4 to 7, and from negative infinity to 7. The tutorial discusses the use of open and closed points, as well as parentheses and brackets, to represent intervals. It also demonstrates how to check if specific values fall within these intervals.

What is the main method used to determine if values are within given intervals?

• Algebraic equations

• Graphical representation

• Statistical analysis

• Numerical approximation
