Functions (Algebra II)?

Question

I solved this problem and wasn't sure if I was correct or not. Can you please explain how you did this problem? If my answer is correct then just tell me I am correct. Thanks so much for your help!

Find f(g(x)) if f(x)= 4x^2 + 2 and g(x)= 3x - 1

My answer is 36x^2 -24x + 6.

Thanks again!

Answer 1

I'm sorry Forrest is wrong, the first person is right.

(3x)^2 is not 3x^2 it is 9x^2

Answer 2

I remember these! Alright, so plug in 3x-1 for 4x^2: Your answer is :

4(3x-1)^2 +2

Answer 3

your answer is wrong sorry

the answer is with the work

4(3x-1)^2+2

4(3x^2-6x+1)+2

12x^2-6x+6

3(4x^2-2x+3)

Answer 4

4(3x-1)^2 + 2

4(9x^2 - 6x + 1) + 2

36x^2 - 24x + 6

Yes, you're correct.

Answer 5

Correct.
