$\text{Set Builder Notation: } \{y|y\lt6\} \\\text{Interval Notation: } (-\infty,6)$
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 $\ge.$
