\( f \circ g(x) = 6x - 5 \)
Solución
1. Write the composition \( f \circ g(x) \) as:
\[
f \circ g(x) = f(g(x))
\]
2. Substitute \( g(x) = 2x-3 \) into \( f(x) = 3x+4 \):
\[
f(g(x)) = 3(2x-3) + 4
\]
3. Distribute the \( 3 \) and then simplify:
\[
3(2x-3) + 4 = 6x - 9 + 4 = 6x - 5
\]
The final result is:
\[
f \circ g(x) = 6x - 5
\]

To find the composition \( f \circ g(x) \), we need to substitute \( g(x) \) into \( f(x) \). First, we calculate \( g(x) \): \[ g(x) = 2x - 3. \] Next, we substitute \( g(x) \) into \( f(x) \): \[ f(g(x)) = f(2x - 3). \] Now, recall that \( f(x) = 3x + 4 \). So, substituting \( 2x - 3 \) into \( f \): \[ f(2x - 3) = 3(2x - 3) + 4. \] Now simplify: \[ = 6x - 9 + 4, \] \[ = 6x - 5. \] Therefore, the composition \( f \circ g(x) = 6x - 5 \).
