Here we look at a function as a mapping diagram. The inputs to the function g are along the real number line a the top, the outputs of g are on the real number line in the middle. The green point A ...

Euler and Venn diagrams are used to visualise the relationships between sets. Both typically employ circles to represent sets, and areas where two circles overlap represent subsets common to both ...

The complement of set B, B’, contains all the elements that are not in set B. \(P’\) is the complement of set \(P\). The intersection of one set and the complement of another set identifies elements ...
