The value of

a

in order that

f(x)=\sqrt{3} \sin x-\cos x-2 a x+b

decreases for all real value of

x

, is given by

View answer and explanation

Correct option: B

a \geq 1

Option B (

a \geq 1

) is correct because for the function to decrease for all real values of x, its derivative must be negative, leading to the inequality

a \geq 1
