Q.
Jawaban:
- f(x) = 80 – 80 + 5x – 4x
f(10) = 80 – 80 + 5(10) – 4(10)
f(10) = 80 – 80 + 50 – 40
f(10) = 0 + 50 – 40
f(10) = 50 – 40
f(10) = 10

Penjelasan dengan langkah-langkah:
f(x) = 80 – 80 + 5x – 4x
f(10) = 80 – 80 + 5(10) – 4(10)
f(10) = 80 – 80 + (5×10) – (4×10)
f(10) = 80 – 80 + 50 – 40
f(10) = 0 + 50 – 40
f(10) = 50 – 40
