Answer
$\text{Set Builder Notation: }
\{y|y\lt6\}
\\\text{Interval Notation: }
(-\infty,6)$
Work Step by Step
The given inequality, $
y\lt6
,$ can be written in the following formats:
\begin{array}{l}\require{cancel}
\text{Set Builder Notation: }
\{y|y\lt6\}
\\\text{Interval Notation: }
(-\infty,6)
.\end{array}
In the graph, a hollowed dot is used for $\lt$ or $\gt.$ A solid dot is used for $\le$ or $\ge.$
