Q.f(x) = 4x + 9f(a) = 33nilai a?nt: hikss, q lanjut nanti (kalo g lupa)​

Penjelasan dengan langkah-langkah:

▶Mencari nilai a :

• 4a + 9 = 33
• 4a = 33 – 9
• 4a = 24
• a = 24/4
• a = 6

▶Pembuktian :

• f(x) = 4x + 9
• f(6) = 4(6) + 9
• f(6) = (4.6) + 9
• f(6) = 24 + 9
• f(6) = 33 ✓ Terbukti

Jawaban:

nilai a?

• a = 4x + 9 = 33
• a = 33 – 9
• a = 24/4
• a = 6

________

Jadi, nilai a adalah 6

________

Pembuktian

• f(x) = 4x + 9
• f(6) = 4(6) + 9
• f(6) = 24 + 9
• f(6) = 33
