Diketahui (f o g)(x) = 4x²-10x+ g dan g(x) = 2x + 3 Tentukan Fungsi F(x)

bantu jawab pliss​

(fog)(x) = 4x² - 10x + 9

f(g(x)) = 4x² - 10x + 9

f(2x + 3) = 4x² - 10x + 9

Misal y = 2x + 3 maka x = (y - 3)/2

f(y) = 4((y - 3)/2)² - 10((y - 3)/2) + 9

= 4((y² - 6y + 9)/4) - 5(y - 3) + 9

= y² - 6y + 9 - 5y + 15 + 9

= y² - 11y + 33

f(x) = x² - 11x + 33
