(SPAM 7037 – 6037)

Jawaban:

Jika f(x) = 6x + 9x

Tentukan:

f(3) = …

f(4) = …

penyelesaian :

f(3) = 6(3) + 9(3)

f(3) = 18 + 27

f(3) = 45

f(4) = 6(4) + 9(4)

f(4) = 24 + 36

f(4) = 60

Penjelasan dengan langkah-langkah:

f(x) = 6x + 9x

Tentukan:

f(3) = 6(3) + 9(3)

f(3) = (6×3) + (9×3)

f(3) = 18 + 27

f(3) = 45

f(4) = 6(4) + 9(4)

f(4) = (6×4) + (9×4)

f(4) = 24 + 36

f(4) = 60
