solne fix) = at tana for – 360s ne 360° @ at a - 270, – go, go, 270 fln) sa so thise point are vertical asymptotes 6 the grapsolhu fin) = ws (2x+ 2) osaan let gen) = cos a. gen et agla) a Now fin) = cos(2(n+1)). compress along a aniq & times and shif6 Y = Acos Blt-1) tc. A 8 bent because man y = 18, min=a. A = 18-2 = 8 means y = cost is expanded 8 times along 3 аш с. graph
