    The maximum and minimum values of the function \[|\sin 4x+3|\]are

    A)            1, 2

    B)            4, 2

    C)            2, 4

    D)            ? 1, 1

    Correct Answer: B

    Solution :

               Here \[f(x)=|\sin 4x+3|\]            We know that minimum value of \[\sin x\] is ?1 and maximum  is 1.            Hence minimum \[|\sin 4x+3|\,=\,|-1+3|=2\] and maximum \[|\sin 4x+3|=|1+3|=4\].
