diketahui f(x) = x-2, g(x) = 3-4x, dan h(x) = 2x+5. jika (fogoh)^1(a) = 2, nilai a =...

[tex] Komposisi \: Fungsi [/tex]

jika f (x) = x - 2
g (x) = 3 - 4x
h (x) = 2x + 5

f (g ( (h (a)))) -¹ = 2 ←→ f (g ( (h (2)))) = a

a = f (g ( (h (2)))) = f (g ( (4 + 5)))
= f (g ( (9)))
= f (3 - 36)
= f (-33)
= -33 - 2
= -35 ✔️

jadi nilai a = -35
jawaban B.
