dik: f(x) = x² -2x - 3, g (x) = x + 1 dan h(x) = 3 - 2x (utk soal 1-5) 1. (g+h) (x)= 2. (f+g)(x)= 3. (f-h)(x)= 4. (g.h)(x)= 5. ( [tex] \frac{f}{g} [/tex] ) (x)

Bab Fungsi
Matematika SMP Kelas VIII

1] (g + h) (x)
= x + 1 + 3 - 2x
= 4 - x

2] (f + g) (x)
= x² - 2x - 3 + x + 1
= x² - x - 2

3] (f - h) (x)
= x² - 2x - 3 - 3 + 2x
= x² - 6

4] (g . h) (x)
= (x + 1) (3 - 2x)
= 3x - 2x² + 3 - 2x
= -2x² - x + 3

5] (f / g) (x)
= (x² - 2x - 3) / (x + 1)
= ((x - 3) (x + 1)) / (x + 1)
= x - 3

maaf jika salah,smoga mmbantu,klo bisa jadiin yg terbaik ya ❤
