$ 0\leq x \lt 1$. See the figure below.

Work Step by Step

The given interval uses a bracket on the left and a parenthesis on right so its equivalent inequality notation would involve $\leq$ on the left end and $\lt$ on the right. Thus, the given interval can be written as $ 0\leq x \lt 1$. To graph, plot solid dot at $ x=0$ and a circle at $x=1$, then shade the region in between. See the figure below.
