Step-by-step explanation:
Since we have given that
[tex]x\geq 3[/tex]
It is shown in the figure below:
1`) Red color part showed that x is greater and equal to 3.
2) it is parallel to y-axis as [tex]x\geq 3[/tex] so, it is atleast x=3 so it will become parallel to y-axis.
3) As Right part of x is shaded :
Because if we apply the "Zero-text":
[tex]Put\ x=0\\\\0\geq 3\\\\\text{ it is false}[/tex]
So, it must be shaded away from the origin.
