Answer:

The value of f(g(3) =  1,008

Step-by-step explanation:

Step:-1

Given f(x) =[tex]3 x ^ 2 + 2 x[/tex]

and g(x) = 3x+9

      h(x) = 12+x

Given g(x) = 3x+9

  put x =3

      g(3) = 3(3)+9

       g(3) = 18

Step :-(2)

f(g(3)) = f(18)

f(g(3) = 3(18)^2 +2(18) (since f(x) =[tex]3 x ^ 2 + 2 x[/tex])

        = 1,008

Final answer:-

The value of f(g(3) =  1,008
