4. 1. F(x) = 2x -1, g(x) = X - 2, maka ( fog ) (x) = ....2. F(x) = x+1, g(x) = 3x , maka (gof)(x) = ....3. Mean dari data : 3, 4, 8, 7, 4, 8, 4, 9, 10, 8, 3, 5, 12, 74. Median dari data : 3, 4, 8, 7, 4, 8, 4, 9, 10, 8, 3, 5, 12, 7Tolong, bantu saya!
2) f (x) = 2x - 1 dan g(x) = x - 2
f o g (x) = f { g(x,) }
= f (x - 2)
= 2(x - 2) - 1
= 2x - 4 - 1
= 2x - 5
2) f (x) = x + 1 dan g(x) = 3x
g o f (x) = g { f(x) }
= g (2x - 1)
= 3(2x - 1)
= 6x - 3
3) urutkan data :
3,3,4,4,4,5,7,7,8,8,8,9,10,12
Mean = (3.2+4.3+5+7.2+8.3+9+10+12) /14
= (6+12+5+14+24+9+10+12) / 14
= 92/14
= 6 8/12.
= 6 2/3
