Question

The shaded part of the number line in given figure can also be represented as



(a) $x\in \left(\frac{9}{2},\infty \right)$

(b) $x\in \left[\frac{9}{2},\infty \right)$

(c) $x\in \left[-\infty ,\frac{9}{2}\right)$

(d) $x\in \left(-\infty ,\frac{9}{2}\right]$

Answer 1

Since shaded part includes $\frac{9}{2}$ and every point after $\frac{9}{2}$
∴ Shaded region can be represented by $\left[\frac{9}{2},\infty \right)$
Hence, the correct answer is option B.
