Question

The correct representation of the set of all real numbers greater than or equal to 2 is given by

• A. $(2,\infty )$
• B. $(2,\infty ]$
• C. $[2,\infty )$
• D. $[2,\infty ]$

Answer 1

The correct option is C $[2,\infty )$

For including 2 in the interval we need to have closed brackets next to 2 and $\infty$ is always accompanied by open brackets. Hence, the correct option is $C,[2,\infty )$
