F(x) = 5x + 10x – x^2 f(5) = ​

Penjelasan dengan langkah-langkah:

f(x) = 5x + 10x – x^2

f(5) = 5(5) + 10(5) – (5²)

f(5) = (5 × 5) + (10 × 5) – (5 × 5)

f(5) = 25 + 50 – 25

f(5) = 75 – 25

f(5) = 50

Jawaban:

f(x) = 5x + 10x – x²

f(5) = 5(5) + 10(5) – 5²

f(5) = 25 + 10(5) – (5 × 5)

f(5) = 25 + 50 – 25

f(5) = 75 – 25

f(5) = 50
