The problem provided is asking for the inverse of the composition of two functions, $(g \circ f)^{-1}(x)$, where:

• $g(x) = 3x^2 - 3x - 1$
• $f(x) = 4x - 6$

Steps to solve:

1. Find $g(f(x))$: To find $g(f(x))$, we substitute $f(x)$ into $g(x)$.

   $g(f(x)) = g(4x - 6) = 3(4x - 6)^2 - 3(4x - 6) - 1$

2. Simplify the expression for $g(f(x))$: Let's expand $(4x - 6)^2$:

   $(4x - 6)^2 = 16x^2 - 48x + 36$

   Now substitute back into $g(f(x))$:

   $g(f(x)) = 3(16x^2 - 48x + 36) - 3(4x - 6) - 1$ Expanding each term: $= 48x^2 - 144x + 108 - 12x + 18 - 1$ Simplifying the constants and the linear terms: $= 48x^2 - 156x + 125$

   Therefore, $g(f(x)) = 48x^2 - 156x + 125$.

3. Find the inverse: Now, we need to find the inverse of the function $g(f(x)) = 48x^2 - 156x + 125$. To do this, we solve for $x$ in terms of $y$:

   $y = 48x^2 - 156x + 125$

   This is a quadratic equation, and solving for $x$ will give us the inverse.
