Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:
So we need to find the entire interval at which this function positive. Put another way:
By using graphing tool, we get the graph shown below. As you can see:
- The function decreases from
- The function increases from
- The graph of the function is a parabola that opens up.
But what is really importan in this problem is that:
- The function is positive over the interval
At this interval the function is positive, that is,
Standard equation of the graph of a parabola:

Step-by-step explanation:
The number lines to make selection from are missing from the question.
<em>However, I've attached 4 number lines, each of which represents each of the given irrational numbers (see attachment)</em>
<em></em>
<u>Number: 2.1823912</u>
This is represented by number line 1
Each point of number line 3 is 0.001 units starting from 2.18;
The point which the red dot is located is between 2.182 and 2.183, but the dot is closer to 2.182.
<em>2.1823912 and 2.1829391321 satisfy this property but number line 2 represents 2.1829391321 (see below for explanation)</em>
So: 2.1823912 is represented by number line 1
<u></u>
<u>Number: 2.1829391321</u>
This is represented by number line 2.
Each point of number line 3 is 0.0001 units starting from 2.182;
The point which the red dot is located is between 2.1829 and 2.1830, but the dot is closer to 2.1829.
From the list of given numbers, only 2.1829391321 satisfy this property.

<u>Number: 2.18112...</u>
This is represented by number line 3.
Each point of number line 3 is 0.01 units starting from 2.11;
The point which the red dot is located is between 2.18 and 2.19.
If number lines 1 and 2 represent 2.1823912 and 2.1829391321, respectively, then number line 3 represents 2.18112.
<u></u>
<u>Number: 2.364125 </u>
This is represented by number line 4.
Each point on this number line is 0.1 unit starting from 2.0;
The point which the red dot is located is between 2.30 and 2.40. From the list of given numbers, only 2.364125 satisfy this property.
