Ada yang bisa nomer 16,17,18,19?

16 . jawab: (f+g)(x) = 3/x+2 + 5/x²+x-2
= 3(x²+x-2)+5(x+2) / (x+2)(x²+x-2)
= (x+2)(3x-3+5) / (x+2)(x²+x-2)
=(3x+2) / (x²+x-2)
jawabannya c.

17. jawab: (g/h)(x) = x²+9x+20 / -x-4
=(x+4)(x+5) / -(x+4)
= -(x+5) = -x-5
jawabannya a.

18. jawab: h(x) = (f.g)(x)
h(x) = (2x-1)(3x+4)= 6x²+5x-4

h(x-1) = 6(x-1)²+5(x-1)-4
= 6(x²-2x+1) + 5x-5-4
=6x²-7x-3
jawabannya b.

19. (f o g)(x) = (f(-x+3))
=(-x+3)²+5(-x+3)+4
=x²-6x+9-5x+15+4
=x²-11x+28
awabannya d.
