1. We are given the functions
   $$
   f(x) = 3x + 4 \quad \text{and} \quad g(x) = 2x - 3.
   $$

2. To find $$ f \circ g(x) $$, we substitute $$ g(x) $$ into $$ f(x) $$:
   $$
   f \circ g(x) = f(g(x)) = 3(2x - 3) + 4.
   $$

3. Distribute $$ 3 $$ in the expression:
   $$
   3(2x - 3) = 6x - 9.
   $$

4. Add $$ 4 $$ to get:
   $$
   f \circ g(x) = 6x - 9 + 4.
   $$

5. Combine like terms:
   $$
   f \circ g(x) = 6x - 5.
   $$
$$ f \circ g(x) = 6x - 5 $$
