Question

Find the union, AUB, for of the following pair of sets. Enter "DNE" for the empty set.A = (-∞, 10), B = [6, ∞)

Answer 1

Given:

$\begin{gathered} A=(-\infty,10) \\ \\ B=[6,\infty) \end{gathered}$

Find-:

Value of the

$A\cup B$

Explanation-:

Value of AUB is:

That means all value of A and B is included

So,

$\begin{gathered} A=(-\infty,10) \\ \\ B=\lbrack6,\infty) \end{gathered}$

Value is:

$A\cup B=(-\infty,\infty)$

That means value is negative infinity to positive infinity.
