Answer
$[0, \frac{1}{2}]$
Refer to the image below for the graph.
Work Step by Step
The inequality represents the numbers that are greater than or equal to $0$ but not more than $\frac{1}{2}$.
$0$ is included so a bracket will be used.
$\frac{1}{2}$ is included so a bracket will be used.
Thus, the equivalent interval notation of the given inequality is:
$[0, \frac{1}{2}]$
To graph the inequality, plot solid dots at $0$ and $\frac{1}{2}$.
Then, shade the region between the two.
