The graph of the equation given by y=-cosu00b3u03b8 will be as follows:

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 ,
