Question

Which of the following represents the set "all values of x greater than or equal to −1 and less than 2" in set builder notation?
A. {x | 2 < x ≤ −1}

B. {x | −1 ≤ x < 2}

C. {x | x < 2}

D. {x | −1, 0, 1, 2}

Answer 1

im  thinkking B because to me it just makes most sense

Answer 2

Answer:  B. {x | −1 ≤ x < 2}

Step-by-step explanation:

Sign we use to denote less than '<' .

Sign we use to denote greater than or equal  : $'\geq'$

The expression to show all values of x greater than -1 : $-1 \leq x$

The expression to show all values of x less than 2 : $x<2$

Now , the expression is used to show  "all values of x greater than or equal to −1 and less than 2".

{x | −1 ≤ x < 2}

So , the correct answer : B. {x | −1 ≤ x < 2}
