Question

List the element of this set. C= {-2<x>8}

Answer 1

I want to confirm the intended notation. Do you mean
- C = { x | -2 < x < 8 } (all x strictly between -2 and 8),
or something else like C = { x | -2 < x and x > 8 } ?

If you mean C = { x | -2 < x < 8 }:
- As a set of real numbers: C = (-2, 8) (uncountably many elements, every real number strictly between -2 and 8).
- If you want the integer elements of C: { -1, 0, 1, 2, 3, 4, 5, 6, 7 }.

If you meant the other reading (-2 < x > 8), that simplifies to x > 8 (so all real numbers greater than 8). Tell me which interpretation you want and I’ll give the answer accordingly.
