Question

If P = (-1, 0, 1, 2, 4} and Q = (4, 5, 6}, find Pu Q.O (-1, 0, 1, 2, 4, 5, 6}Of0 (4)O (-1, 0,1, 2, 4}

Answer 1

Statement Problem: If;

`P=\mleft\lbrace-1,0,1,2,4\mright\rbrace,Q=\mleft\lbrace4,5,6\mright\rbrace`

Find;

`P\cup Q`

Solution:

The union of two sets is a set containing all elements that are in the two sets.

The elements that make up a set can be any kind of mathematical objects: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other sets.

Thus, the union of set P and set Q is;

`P\cup Q=\mleft\lbrace-1,0,1,2,4,5,6\mright\rbrace`
