\( f \circ g(x) = 6x - 5 \)
Solución
1. Write down the definition of the composition \( f \circ g(x) \):
\[
f \circ g(x) = f(g(x))
\]
2. Substitute the function \( g(x) = 2x - 3 \) into \( f(x) \):
\[
f(g(x)) = f(2x-3) = 3(2x-3) + 4
\]
3. Distribute and simplify the expression:
\[
3(2x-3) + 4 = 6x - 9 + 4 = 6x - 5
\]
Thus, the composed function is:
\[
f \circ g(x) = 6x - 5
\]

The Deep Dive
To find \( f \circ g(x) \), we need to compute \( f(g(x)) \). First, let's substitute \( g(x) \) into \( f(x) \): \[ g(x) = 2x - 3 \] Now substitute this into the function \( f \): \[ f(g(x)) = f(2x - 3) = 3(2x - 3) + 4 \] Now, distribute the 3: \[ = 6x - 9 + 4 \] Combine like terms: \[ = 6x - 5 \] Thus, \( f \circ g(x) = 6x - 5 \).
