Refer to the attached image below for the graph. The interval notation equivalent of the given set is $(-\infty, -1)$.
Work Step by Step
The given set covers the x-values that are less than $-1$. This means that its graph will be the region to the left of $-1$. To graph the set, plot a hollow dot (or a hole) at x=-1 then shade the region to its left. (refer to the attached image for the graph) The interval notation equivalent of the given set is $(-\infty, -1))$.
