Question

If $x\ge -4$, then $x+1\ge$ is

• A. -2
• B. -3
• C. -4
• D. -1

Answer 1

The correct option is B -3

Given, $x\ge -4$
There will be a closed circle on -4 as value of $x$ is equal to -4.

Arrow will head towards right to the number line because $x$ is greater than -4.

Number line representation of $x+1$
Add 1 to the both side
$x+1\ge -4+1$
$x+1\ge -3$
There will be a closed circle on -3 as value of $x$ + 1 is equal to -3.
Arrow will head towards right to the number line beacuse $x$ + 1 is greater than -3.


We can see on the number line, possible values of $x+1$ are greater than or equal to $-3$.
$\therefore x+1\ge -3$
