How to find interval notation?
The easiest way to find interval notation is to first draw a graph on a number line as a visual representation of what’s going on in the interval. If the endpoint of the interval isn’t included in the solution (for < or >), the interval is called an open interval.
What does interval notation look like?
Interval notations usually look like a mirror image. On the left side is a negative number, and on the right side is that same number on the positive end of the scale. They’re used to graphically illustrate a number of functions, such as laboratory results, ranges and points between two numbers.
What does interval notation mean?
Interval notation is a way to describe continuous sets of real numbers by the numbers that bound them. Intervals, when written, look somewhat like ordered pairs.
