☔ Oi, Thomas. Vamos visualizar cada um dos  dois intervalos e a união deles:

⠀

$\large\begin{array}{l}\sf A: ~~~~~~~ \green{\blacktriangleleft\!\!{\textsf{------------}}\!\!\!\:\!\underset{-1}{\circ}\!\!\!{\textsf{---------------------}}\!\!\!\:\!\underset{3}{\bullet}\!\!\!{\textsf{-----------------}}\!\!\!\blacktriangleright}\end{array}$

⠀

$\large\begin{array}{l}\sf B:~~~~~~~ \green{\blacktriangleleft\!\!{\textsf{--------------------}}\!\!\underset{2}{\circ}\!\!{\textsf{---------------------}}\!\!\!\!\underset{5}{\bullet}\!\!\!{\textsf{-----------}}\!\!\!\blacktriangleright}\end{array}$

⠀

$\large\begin{array}{l}\sf A \cup B:~ \green{\blacktriangleleft\!\!{\textsf{------------}}\!\!\!\:\!\underset{-1}{\circ}\!\!\!{\textsf{----------------------------}}\!\!\!\!\underset{5}{\bullet}\!\!\!{\textsf{------------}}\!\!\!\blacktriangleright}\end{array}$

⠀

$\green{\boxed{\rm~~~~\gray{A \cup B}~~\pink{=}~~\blue{ \{x \in \mathbb{R}~|~-1 < x \leq 5\}}~~~}}$ ✅
