The inequality given is:
[tex]2x+1\ge3[/tex]
Let's solve for x:
[tex]\begin{gathered} 2x\ge3-1 \\ . \\ x\ge\frac{2}{2} \\ . \\ x\ge1 \end{gathered}[/tex]
The solution set of this inequality is the set of all numbers bigger or equal than 1.
Thus, the correct answer is option A, where we can see that the values start at 1 and goes to positive infinity.
