Help needed asap! Must be answered using interval notation!

Answer 1

In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:

[-1, 3).

How to write the interval of values in the graph using interval notation?

First, remember that the symbols ( and ) are used for ends that do not belong to the interval.

For example, if our interval is 1 < x < 2

1 and 2 do not belong to the solution interval, thus, the solution interval is (1, 2).

While [ and ] are used when the ends belong. For example, in:

1 ≤ x ≤ 2

The interval notation is [1,  2]

And in:

1 < x ≤ 2

(1, 2]

And so on.

On the number line, the notation is:

• Colored dot: the point belongs to the interval.
• White dot: the point does not belong to the interval.

In this case, we have a colored dot at -1 and a white dot at 3, then the interval notation for that graphed interval will be:

[-1, 3).
