असमानता \(y\leq 0\) का आलेख कौन सा अर्ध-तल दिखाता है?
Which half-plane is represented by \(y\leq 0\)?
Explanation opens after your attempt
Correct Answer
A. निचला अर्ध-तल, (x)-अक्ष सहितLower half-plane including the (x)-axis
Concept
In \(y\leq 0\), (y) is zero or negative, so the (x)-axis and the lower side are included. Remember (y=0) is the (x)-axis in exams.
Why this answer is correct
The correct answer is A. निचला अर्ध-तल, (x)-अक्ष सहित / Lower half-plane including the (x)-axis. In \(y\leq 0\), (y) is zero or negative, so the (x)-axis and the lower side are included. Remember (y=0) is the (x)-axis in exams.
Exam Tip
\(y\leq 0\) में (y) शून्य या ऋणात्मक है, इसलिए (x)-अक्ष और नीचे का भाग शामिल है। परीक्षा में (y=0) को (x)-अक्ष समझें।
