Answer:
3x^2 + 4x + 3
Explanation:
we can use this information to find g(x) in terms of f(x).
substitute f(x) = 3x-1 into f(g(x)) = 9x^2 + 12x + 8, we get:
3g(x) - 1 = 9x^2 + 12x + 8
Now, we can solve for g(x) by isolating it on one side of the equation:
3g(x) = 9x^2 + 12x + 9
g(x) = 3x^2 + 4x + 3
therefore g(x) is equal to 3x^2 + 4x + 3
