Answer:

The value of f(g(3) = 1,008

Step-by-step explanation:

<u>Step:-1</u>

Given f(x) = $3 x ^ 2 + 2 x$

and g(x) = 3x+9

h(x) = 12+x

Given g(x) = 3x+9

put x =3

g(3) = 3(3)+9

<u> g(3) = 18</u>

<u>Step :-(2)</u>

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

f(g(3) = 3(18)^2 +2(18) (since f(x) = $3 x ^ 2 + 2 x$ )

= 1,008

<u>Final answer</u>:-

The value of f(g(3) = 1,008
