f(x) = 5x - 3x²
f(2) =....
[D-12 + D-13, 10/10]
f(x) = 5x - 3x²
f(2) = 5(2) - 3(2)²
f(2) = 5(2) - 3(2²)
f(2) = 5(2) - 3(4)
f(2) = (5 x 2) - 3(4)
f(2) = 10 - 3(4)
f(2) = 10 - (3 x 4)
f(2) = 10 - 12
f(2) = -2

Jawaban:
Fungsi komposisi
f(x) = 5x - 3x²
f(2) = ...?
Nilai x = 2 kita substitusi ke;
f(x) = 5x - 3x²
f(2) = 5(2) - 3(2)²
f(2) = 10 - 3(4)
f(2) = 10 - 12
f(2) = -2
Jadi, hasil dari f(2) adalah -2.
