1).F(x)=x^-x-6 g(x)=x+3 h(x)=x+3 Ditanya: a)((fog)oh)(x) b)((fo(goh)(x) c)(fog)oh)(2) d)(f/h)(x) e)(f/h)(2)

a).cari dulu (fog) =(x+3)^2 - (x+3) - 6
                           =(x^2+6x+9) - (x+3) - 6
                           =x^2+6x-x+9-3-6
                           =x^2+5 (hasil fog)
     selanjutnya ((fog)oh)=(x+3)^2+5(x+3)
                                      =(x^2+6x+9)+5x+15
                                      =x^2+6x+5x+15
                                      =x^2+11x+24 (hasil (fog)oh)
