The text in the image appears to be in Indonesian and reads:

**"Hasil dari: (-0,4)∩[3,10] adalah ..."**

This is asking for the result of the intersection of the intervals \((-0.4)\) and \([3,10]\).

In interval notation:

- \((-0.4)\) refers to the open interval, which usually represents the numbers less than \(-0.4\) or greater, but here it's not a standard interval format. 
- \([3, 10]\) represents the closed interval, meaning the set of all numbers from 3 to 10, inclusive.

Since the open interval \((-0.4)\) doesn't seem to form a standard mathematical interval with clear bounds, I would need more clarification on how it's intended.

Would you like to clarify or provide details on how \((-0.4)\) is interpreted in this context? Let me know if you want a deeper explanation or related concepts.

### Tip:
Always pay attention to whether an interval is open or closed, as this affects whether the endpoints are included in the solution set.
