Tolong ya kak... 2 nomer ini aja.. Terserah mau jwb yg mana.. Plissss....tolong.

Bab Fungsi

No 8)

x = {5,4,3,2,1}

f(x) = 9 - x^2

f(5) = 9 - (5)^2 = 9 - 25 = -16
f(4) = 9 - (4)^2 = 9 - 16 = -7
f(3) = 9 - (3)^2 = 9 - 9 = 0
f(2) = 9 - (2)^2 = 9 - 4 = 5
f(1) = 9 - (1)^2= 9 - 1= 8

HP = {-16,-7,0,5,8} ===> A

NO 9)

Jawaban = C

Coba Satu satu ya

f(2) = 2(2) - 3 = 4 - 3 = 1 ( Benar)
f(5) = 2(5) - 3 = 10 - 3 = 7 ( Benar )
f(8) = 2(8) - 3 = 16 - 3 = 13 ( Benar )
Jadi Pilihan = C
