Based on the description provided, the closed point between 4 and 5 indicates that the value at that point is included in the solution set. Since there is a rightward arrow from this point, it suggests that the values greater than or equal to this point are part of the solution.
Since the closed point is just after 4, the inequality should reflect that \( x \) is greater than or equal to 4. The correct inequality would be:
\[ x \geq 4 \]
However, you mentioned that the answer is not \( x \geq 4.5 \), suggesting that the closed point is actually at \( x \) being slightly greater than 4 but less than 4.5. Therefore, the inequality can be formulated as:
\[ x \geq 4 \]
If the closed point is specifically at 4, then that is the correct interpretation because values greater than 4 up to 10 will satisfy the inequality given the rightward arrow.
Hence, if the interpretation is accurate, the final inequality should be:
\[ x \geq 4 \]
If it is further specified that the closed point should not be at or equal to 4.5 but still includes 4, then specifying the closed interval could be an option. If more clarification leads to a different specification, please update accordingly.
