To find the composition $$ f \circ g(x) $$, which means $$ f(g(x)) $$, follow these steps:

Given:
$$
f(x) = 3x + 4 \quad \text{and} \quad g(x) = 2x - 3
$$

**Step 1:** Substitute $$ g(x) $$ into $$ f(x) $$.

$$
f(g(x)) = f(2x - 3)
$$

**Step 2:** Apply the function $$ f $$ to $$ 2x - 3 $$.

$$
f(2x - 3) = 3(2x - 3) + 4
$$

**Step 3:** Distribute and simplify.

$$
3(2x - 3) + 4 = 6x - 9 + 4 = 6x - 5
$$

**Conclusion:**
$$
f \circ g(x) = 6x - 5
$$
$$ f \circ g(x) = 6x - 5 $$
