tolong bantuin buat besok

4. (hog)(x) = h(x² - 3x - 9)
= 4(x² - 3x - 9) - 1
= 4x² - 12x - 36 - 1
= 4x² - 12x - 37
(hog)(-2) = 4(-2)² - 12(-2) - 37
= 16 + 24 - 37
= 3 (D)

5. h(x) = (fog)(x)
h(x) = f(-2x + 1)
h(x) = (-2x + 1) + 3
h(x) = -2x + 4
[tex] {h}^{ - 1} (x) = y = - 2x + 4 \\ y - 4 = - 2x \\ x = \frac{y - 4}{ - 2} \\ {h}^{ - 1} = - \frac{x - 4}{2} [/tex]
maaf kalau salah
