Q. f(x) = 2x³ + 5xf(3) = ​

Jawaban:

Fungsi komposisi

f(x) = 2x³ + 5x

f(3) —> nilai x = 3 substitusi ke;

f(x) = 2x³ + 5x

f(3) = 2(3)³ + 5(3)

f(3) = 2(27) + 15

f(3) = 54+15

f(3) = 69

Penjelasan dengan langkah-langkah:

f(x) = 2x³ + 5x

f(3) =

f(x) = 2x³ + 5x

f(3) = 2(3)³ + 5(3)

f(3) = 2(27) + (5 × 3)

f(3) = (2 × 27) + 15

f(3) = 54 + 15

f(3) = 69
