A.
(f o g)(x) = f(g(x))
= 3√x - 1

(g o f) o h) (x) = g(f(h(x)))
= √3ײ+2-1
= √3ײ+1

b.
(f o g)(4) = f(g(4))
= 3√4-1
= 3.2 - 1
= 5

(f o g)(2) = f(g(2))
= 3√2-1

(f o g)(-2) = f(g(-2))
= 3√-2 - 1
= tidak ada jawaban karena tidak ada hasil akar dari angka < 0

(f o h)(-1) = f(h(-1))
= 3(-1)²+2 - 1
= 3 + 2 -1
= 4

(h o g)(3) = h(g(3))
= (√3)² + 2
= 3 + 2
= 5
