To graph the interval
Solution
To graph the interval
-
Identify the endpoints: The interval
has two endpoints: -8 and -3. Since the interval is open (indicated by the parentheses), the endpoints themselves are not included in the interval. -
Draw the number line: Start by drawing a horizontal line. Mark points on this line for -8 and -3.
-
Indicate the endpoints: Use open circles at -8 and -3 to show that these points are not included in the interval.
-
Shade the region: Shade the area between -8 and -3 to indicate that all numbers between these two points are included in the interval.
The final representation will show an open interval between -8 and -3 on the number line, with open circles at both -8 and -3.

To graph the interval
Think of this interval like a “no-entry zone” between two numbers where -8 and -3 are the boundaries! Any number between these two values is welcome to join the party, but the parties at -8 and -3 themselves are closed, hence the open circles!
