Jawaban:

(x) = 2/9x²-22/9x+ 101/9

Penjelasan dengan langkah-langkah:

Diketahui:

g(x) = -3x+4

fog (x) = 2x²+2x+5

Ditanya :

f(x)?

JAWAB:

fog (x) = 2x²+2x+5

f(-3x+4) =2x²+2x+5

misalkan t = -3x+4

x =  \frac{t - 4}{ - 3}

f(t) = 2(-⅓(t-4))²+ 2(-⅓(t-4))+5

f(t) = 2/9(t²-8t+16) – ⅔(t-4)+5

f(t) = 2/9t²-16/9t+ 32/9- ⅔t + 8/3 +5

f(t) = 2/9t²-22/9t+ 101/9

f(x) = 2/9x²-22/9x+ 101/9
