Answer
$x \lt 1$
Refer to the image below for the graph.
Work Step by Step
A parenthesis at 1 ,means $1$ is not included in the set,
An infinity on the left means the graph goes to the left of $1$ without bound.
Thus, the equivalent inequality of the given interval is:
$x \lt 1$
To graph the interval on a number line, hole (or a hollow dot) at $1$ then, shade the region to its left.
(refer to the attached image in the answer part above)
