Question

Define the range of the following:
{-2, 0, 1, 2, 8}
{-3, -2, 0, 1, 2, 3, 4, 5, 8}
All Real Numbers
{-2, 3, 4, 5}

Answer 1

The range is the difference between the highest number and the lowest number in a set of points.

8-(-2)=
8-(-3)=
5-(-2)=

Answer 2

- so i think you missed the ,,All real numbers" - the 3rd set - what about this ?

Answer 3

Oh well thank you for pointing that out @jhonyy9 I didn't see that at 1st.
Well because it is all real numbers you would show it after you subtract it to get the range so I would believe it'd be: x ≥ 7. Correct me if I am wrong.
