Question

All real numbers at most 6 units from 0

Answer 1

Please include all of the instructions.  For example:  "Write a set representing all real numbers at most 6 units from the origin, 0."

"At most 6 units to the right of 0" brings us to x=6, and "at most 6 units to the left of 0" brings us to x = -6.

Thus, the interval of interest is [-6,6].
