Diketahui:F(X)=2x-5 G(X)=X+2/2 Dit:a.(FoG)(X)= b.(GoF)(X)=

FoG= (2X-5) + 2/2 = 2X+5+1 = 2X+6
GoF= 2(X+2/2) - 5 = 2(X+1) - 5 = 2X+2-5 = 2X-3

F (x) = 2x - 5
G (x) = (x + 2) / 2

Fog (x) = f (g (x))
= f ((x + 2) / 2)
= 2 ((x + 2) / 2) - 5
= x + 2 - 5
= x - 3

Gof (x) = g (f (x))
= g (2x - 5)
= (2x - 5 + 2) / 2
= (2x - 3) / 2
= x - 3/2
