- The set notion will be written as {x∈ℝ | -0.25≤x≤0.5}
- The interval notion will be -0.25≤x≤0.50
Interval notation is way of showing that some values fall in between sets of numbers.
Given the set {-0.25,0,0.25,0.50}, the set notion will be written as;
{x∈ℝ | -0.25≤x≤0.5}
ℝ means that the values in the given set are real numbers. Also, note that the sets are inside curly brackets compared to the interval notion.
The interval notion will be -0.25≤x≤0.5. Interval notions are not always in curly brackets.
