Jawaban:
1.
fogoh(x)
= fog(h(x))
= fog(x-4)
= f(g(x-4))
= f((x-4)+2)
= f(x-2)
= (x-2)²
= x²-4x+4
2a.
(fog)(x)
= f(g(x))
= f(x+2)
= (x+2)²
= x²+4x+4
(fog)oh(x)
= fog(h(x))
= fog(x-4)
= (x-4)²+4(x-4)+4
= x²-4x+4
2b.
goh(x)
= g(h(x))
= g(x-4)
= g(x-4)
= (x-4)+2
= x-2
fo(goh)(x)
= f(x-2)
= (x-2)²
= x²-4x+4
