Lower bound is 17.6 and upper bound is 17.8
The lower bound of 3.0 is 3.0
The answer is B.
You cannot list them: unless the inequality is trivial, since there are infinitely many real numbers in any range. You need toidentify the lower bound;determine whether or not the lower bound is included (
What is the lower and upper bound of 9.3 in 1 s.f.?
The lower bound is 16.35
The lower bound is 0.5 less and the upper bound is 0.5 more.

If the range is the real numbers, it has a lower bound (zero) but no upper bound.
