Question

Union and intersection.
The sets F and H are defined as follows.
F={y|y(less than or equal to)1}
H={y|y>5}

Write F(union)H and F(Intersection)H using interval notation.

Answer 1

Anyone?

Answer 2

1. Union Is:

\[F \cup H = (y|y \in (-\infty, 1] \cup (5, \infty))\]

2. Intersection is:

\[F \cap H = \phi = 0\]

Where,
\[\phi\] is a empty set...
