Dik: f(x)=xpngkt2-x+1 g(x)=x-2 Dit:f(g(x)) g(f(x))

➡f(g(x)) = f(x-2)

= (x - 2)² - (x - 2) + 1
= x² - 4x + 2 - x + 2 + 1
= x² - 5x + 5

➡g(f(x)) = g(x² - x + 1)

= (x² - x + 1) - 2
= x² - x - 1

Sub Bab. : Fungsi

Pembahasan:

A. f(g(x)) = f(x-2)
= (x-2)²-(x-2)+1
= x²-4x+2-x+2+1
= x²-4x-x+2+2+1
= x²-5x+4+1
= x²-5x+5. → Jwbnya

B. g(f(x)) = g(x²-x+1)
= (x²-x+1)-2
= x²-x-1 → Jwbnya
