Asked by Anon
Apologies. I am heavily dyslexic and I find this very difficult to grasp.
I have two graphs with x and r as the variables. I am trying to state the range in which the values of this graph meet a certain criteria.
For graph 1 I have found the range to be +-3 to +-11.1.
And graph 2 has a range of +-2.5 to +-9.8.
Would (-11.1,-3]U[3,11.1) and (-9.8,-2.5]U[2.5,9.8) represent this?

Well, I do not know how you got the range as ± 3 to ± 11.1.
The interpretation of your answer is
-11.1 (excluding) to -3 (including)
together with
3 (including) to 11.1 (excluding).
This means that (-3,3) is excluded from the range. Confirm that this is the case. If the graph shows that (-3,3) is included in the range, then it is simply (-11.1,11.1) (where the two limits are excluded).
It is much easier if we can see the graph.
Please follow the same reasoning for the second problem.
