Question

Diketahui f(x) = 2x-3 dan (gof)(x) = 4x²-16x+18 maka g(x)=...
Yang jawab aku beri jawaban terbaik

Answer 1

F(x) = 2x- 3
gof(x) = 4x² - 16x + 18
g(2x-3)= 4x² -16x + 18
g(x) = 4((x+3)/2 )² - 16 ((x+3)/2) + 18
g(x) = 4(x+3)² /4 - 8(x+3) + 18
g(x) = (x+3)² - 8(x+3) + 18
g(x)=  x²+6x + 9 - 8x - 24 + 18
g(x) = x² - 2x+ 3
