Either. Whether a particular number is open or closed depends on the set in question, not the specific number.

What is the difference of an Open and closed circle number line?

With an open circle, the number at which the circle is is NOT included in the dataset; with a closed circle it is. For example if a line is drawn on the number line between 0.5 and 1.5 with a closed circle at 0.5 and an open circle at 1.5, then it represents the numbers between 0.5 and 1.5 including 0.5 but excluding 1.5; this range is the numbers which round to 1 to the nearest whole number.

Between 1 and 3include 1 and 3?

If you are referring to a number line: If it is between 1 and 3, then no you would not include 1 and 3... If the notation is [1,3] then 1 and 3 are included (both 1&3 would be closed circles on the # line) If the notation is (1,3) then 1 and 3 aren't included (1 & 3 would be open circles on the number line) If the notation is [1,3) 1 is included 3 is not (1 is a closed circle, 3 is an open circle on # line) If the notation is (1,3] 1 is not included, 3 is included (1 is open circle, 3 is closed circle on the # line)

How do you graph x is greater than negative four?

We assume you are graphing on a number line, not an x-y plane. Draw an "open" circle (not filled in) at -4, and a line from it across to the right end of the number line. Put an arrow on the end of the line to show that the graph continues to the right.


Which do you use an open circle or closed cirle for graphing inequalities?
