Diketahui f(x) = x2 dan g(x) x + 2

● Materi : Fungsi.

● Kode Kategorisasi: 10.2.3.

Penjelasan dengan langkah-langkah:

a

(f + g)(x) = f(x) + g(x)

(f + g)(x) = x^2 + x + 2

(f + g)(3) = (3)^2 + (3) + 2

(f + g)(3) = 9 + 3 + 2

(f + g)(3) = 14

b

(f – g)(x) = f(x) – g(x)

(f – g)(x) = x^2 – (x + 2)

(f – g)(x) = x^2 – x – 2

(f – g)(1) = (1)^2 – (1) – 2

(f – g)(1) = 1 – 1 – 2

(f – g)(1) = -2
