Jika f(x)=2x+6 dan g(x)=2x2+6x-7 maka (f'g)(x)=...? f(x) = 2x+6 (fog) = 2x²+6x-7 (fog) = f(g(x)) 2x²+6x-7 = 2g(x) + 6 2g(x) = 2x²+6x-13 g(x) = (2x²+6x-13)/2 g(x) = x²+3x-5 D. Jika g(x)=x+1dan f(x)=x2+3x+1 maka (pg)(x)=..? g(x)=x+1 misalkan g(x) = a a = x + 1 x = a - 1 (fog)(x)=x²+3x+1 f (g(x)) =x²+3x+1 f (a) = (a - 1)²+ 3(a - 1) + 1 f(a) = a² - 2a + 1 + 3a - 3 + 1 f(a) = a² + a - 1 f (x) = x² + x - 1
