Question:
The shaded part of the number line in given figure can also be represented as.png)
(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) $x \in\left(-\infty, \frac{9}{2}\right]$
Solution:
Since shaded part includes $\frac{9}{2}$ and every point after $\frac{9}{2}$
$\therefore$ Shaded region can be represented by $\left[\frac{9}{2}, \infty\right)$
Hence, the correct answer is option B.
