परवलय \(y=2x^2-12x+13\) का शीर्ष बिंदु कौन सा है?
What is the vertex of the parabola \(y=2x^2-12x+13\)?
Explanation opens after your attempt
A. ((3,-5))
Concept
Here \(x=\frac{-b}{2a}=\frac{12}{4}=3\). Substituting (x=3) gives (y=-5).
Why this answer is correct
The correct answer is A. ((3,-5)). Here \(x=\frac{-b}{2a}=\frac{12}{4}=3\). Substituting (x=3) gives (y=-5).
Exam Tip
\(x=\frac{-b}{2a}=\frac{12}{4}=3\) है। (x=3) रखने पर (y=-5) मिलता है।
