Q. What interval does this inequality represent?

\newline

-2 \leq x < 3

\newline

Choices:

\newline

(A)

(-2, 3]

\newline

(B)

[-2, 3)

\newline

(C)

(-2, 3)

\newline

(D)

[-2, 3]

Identify Endpoints: Identify the endpoints of the interval for the inequality $-2 \leq x < 3$ . The endpoints are $-2$ and $3$ .
Check Inclusion: Check whether the endpoints are included in the interval. For $-2 \leq x$ , $-2$ is included in the interval, which is denoted by a closed bracket [ or a square bracket. For $x < 3$ , $3$ is not included in the interval, which is denoted by an open bracket ) or a parenthesis.
Determine Interval: Determine the interval that the inequality $-2 \leq x < 3$ represents. Since $-2$ is included and $3$ is not included, the interval is $[-2, 3)$ .
