Question

The sets L and G are given below.

L = (-1,0,2,4,6,7)
G=(-1,3,4,5)
Find the intersection of L and G.
Find the union of L and G.
Write your answers using set notation (in roster form).​

Answer 1

L∩G = {-1,4}

L∪G={-1,0,2,3,4,5,6,7}

Explanation:

L = (-1,0,2,4,6,7)

G=(-1,3,4,5)

Find the intersection of L and G.

Intersection means the common elements in both sets.The intersection of two sets is a new set that contains all of the elements that are in both sets. The intersection is written as L∩G

L∩G = {-1,4}

Find the union of L and G

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets. It is represented by L∪G

L∪G={-1,0,2,3,4,5,6,7}....
