What is the axis of symmetry of the graph of (f(x)=2x-2-8x+1)?
Explanation opens after your attempt
A. (x=2)
Concept
Put (a=2) and (b=-8) in \(x=-\frac{b}{2a}\). This gives (x=2).
Why this answer is correct
The correct answer is A. (x=2). Put (a=2) and (b=-8) in \(x=-\frac{b}{2a}\). This gives (x=2).
Exam Tip
\(x=-\frac{b}{2a}\) में (a=2) और (b=-8) रखें। इससे (x=2) मिलता है।
