Question

if f(x)=3x^2-2x+1 and f(g(x))=12x^2-16x+6
now g(x)=?

Answer 1

f(g)(x)=2(6x^2-8x+3)

Answer 2

12x^2+6=f(g)(x)+16x

Answer 3

no no f(x)=false!!!

Answer 4

f(g(x))

Answer 5

f(g)(x)=false!!

Answer 6

may you solve it?

Answer 7

12x^2-16x+6 = 12x^2 - 12x +3 -4x +2 +1
= 3(4x^2 -4x+1) - 2(2x-1) +1
= 3(2x-1)^2 - 2(2x-1) +1

so
g(x)= 2x-1
