Graph the compound inquality on the number line.
x< 3 or x > 6
To graph the compound inequality "x < 3 or x > 6" on a number line, follow these steps:
1. Draw a straight line with an arrow on both ends to represent the number line.
---->-----|------|-----|------|-----|------|----->
-∞ 3 6 ∞
Label key points on the number line using the numbers mentioned in the inequality. Here, the key points are -∞ (negative infinity), 3, 6, and ∞ (infinity).
2. Plot an open circle at the number 3 because the inequality is "x < 3" (not including 3).
---->-----|-----●|-----|------|-----|------|----->
-∞ 3 6 ∞
3. Draw an arrow to the left of the open circle towards negative infinity to represent the part of the number line where x is less than 3.
---->-----|----->|-----|------|-----|------|----->
-∞ 3 6 ∞
4. Plot an open circle at the number 6 because the inequality is "x > 6" (not including 6).
---->-----|----->|-----●-----|-----|------|----->
-∞ 3 6 ∞
5. Draw an arrow to the right of the open circle towards infinity to represent the part of the number line where x is greater than 6.
---->-----|----->|-----●-----►-----|------|----->
-∞ 3 6 ∞
6. The graph is complete. The shaded sections indicate all the possible values of x that satisfy the compound inequality "x < 3 or x > 6."
