f\left( x \right)

is a polynomial of degree

n\left( { > 2} \right)

and

f\left( x \right) = f\left( {\alpha - x} \right)

, (where

\alpha

is fixed real number), then the degree of

f'\left( x \right)

View answer and explanation

Correct option: B

n - 1

Option B (

n - 1

) is correct because the derivative of a polynomial of degree

n

is a polynomial of degree

n-1
