A pie chart or pie graph is a special chart that uses "pie slices" to show relative sizes of data
The chart is divided into sectors, where each sector shows the relative size of each value.
One way of writing this in set builder notation could be:
Which can be interpreted as:
The set A is the set of any x such that 2≤x≤8 such that half of x is a natural number (N).
There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e. ∈,|,N), it becomes much easier to “read as a sentence”.
Here are a few more ways of writing the set A=2,4,6,8 in set builder notation:
