\( f \circ g(x) = 6x - 5 \)
Solución
Simplify the expression by following steps:
- step0: Multiply the terms:
\(f\left(gx\right)\)
- step1: Multiply the terms:
\(fgx\)
Expand the expression \( 3(2x - 3) + 4 \)
Simplify the expression by following steps:
- step0: Add the terms:
\(3\left(2x-3\right)+4\)
- step1: Expand the expression:
\(6x-9+4\)
- step2: Add the numbers:
\(6x-5\)
To find \( f \circ g(x) \), we need to substitute \( g(x) \) into \( f(x) \).
1. We have the functions:
\[
f(x) = 3x + 4
\]
\[
g(x) = 2x - 3
\]
2. Now, we substitute \( g(x) \) into \( f(x) \):
\[
f(g(x)) = f(2x - 3)
\]
3. Substitute \( 2x - 3 \) into \( f(x) \):
\[
f(2x - 3) = 3(2x - 3) + 4
\]
4. Now, we expand this expression:
\[
= 6x - 9 + 4
\]
\[
= 6x - 5
\]
Thus, the result of \( f \circ g(x) \) is:
\[
f \circ g(x) = 6x - 5
\]

To find \( f \circ g(x) \), you need to substitute \( g(x) \) into \( f(x) \). First, calculate \( g(x) \): \[ g(x) = 2x - 3 \] Now, substitute \( g(x) \) into \( f(x) \): \[ f(g(x)) = f(2x - 3) \] Next, use the definition of \( f(x) \): \[ f(x) = 3x + 4 \] Replace \( x \) in \( f(x) \) with \( 2x - 3 \): \[ f(2x - 3) = 3(2x - 3) + 4 \] Now, simplify: \[ = 6x - 9 + 4 \] \[ = 6x - 5 \] Thus, the result is: \[ f \circ g(x) = 6x - 5 \]
