1. Jawaban andhikahanif
(g o f) (2) = g(f(2))
(g o f) (2) = g(2 + 1 / 2 - 3)
(g o f) (2) = g(3 / -1)
(g o f) (2) = (3 / -1)² + (3 / -1) + 1
(g o f) (2) = 9 - 3 + 1
(g o f) (2) = 7 -
2. Jawaban chelseanatali82
(gof)(x) =(x+1/x-3)^2+(x+1/x-3)+1 =(x^2+2x+1/x^2-6x+9)+(x+1/x-3)+1 jadi gof(2)=(2^2+2(2)+1/2^2-6(2)+9)+(2+1/2-3)+1 =(4+4+1/4-12+9)+(3/-1)+1 =(9/1)+(-3)+1 =9-3+1 =7 semoga membantu:)
