    Answer with explanation:

    The given cosine function is

    y= – cos 3 (theta)= -3 cos A, where , theta =A.

    u2192u2192Domain of Cos A

    = All Real number

    = Period is from (-u03c0 , u03c0)

    Range of Cos A=[-1, 1]

    u2192Domain of Cos 3 A,will be also, all real number.

    Period is from,

    [tex][frac{-pi}{3},frac{pi}{3}][/tex]

    But range of Cos 3A,will be same as ,Cos A which is equal to ,[-1,1].

    u2192Plotted the graph of ,y=-cos 3 A, having cycle ,

    [tex][frac{-pi}{3},frac{pi}{3}][/tex]
