Graphing closed and open dots
WebStep 3: If the weight of the letter is more than 2 oz (not 2 oz exactly because the circle is open) and up to 3 oz (including 3 oz since the circle is closed), then the price is 43 cents. Steps 4-6 follow the same pattern as steps 1-3 described above. As you can see, this graph tells you exactly how much your letter will cost depending on the ... WebThis ray is often called an open ray or a half line. The hollow dot distinguishes an open ray from a ray. ... Figure 6. A graph showing closed interval { x: –1 ≤ x ≤ 2}. Figure 7. A graph showing open interval { x: –2 < x < 2}. If the interval includes only one of the boundaries, then it is called a half‐open interval.
