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 parent radioisotope for the beta decay that produces barium-137 is cesium-137. Cesium-137 decays through beta decay to form barium-137 by emitting an electron and an antineutrino.
If the range is the real numbers, it has a lower bound (zero) but no upper bound.
