कौन सा समीकरण ऊर्ध्व रेखा परीक्षण में असफल होता है?
Which equation fails the vertical line test?
Explanation opens after your attempt
A. \(y^2=x+1\)
Concept
In \(y^2=x+1\), many (x)-values give two (y)-values. So it is not the graph of a function.
Why this answer is correct
The correct answer is A. \(y^2=x+1\). In \(y^2=x+1\), many (x)-values give two (y)-values. So it is not the graph of a function.
Exam Tip
\(y^2=x+1\) में कई (x)-मानों के लिए दो (y)-मान मिलते हैं। इसलिए यह फलन का आलेख नहीं है।
