• в. 5х - 1
• c. 5х - 3
• D. x-3

Answers

Answer
So x-3?
Answered by GPT-4o mini
To find \((f - g)(x)\), we need to calculate:

\[
(f - g)(x) = f(x) - g(x)
\]

Given:

\[
f(x) = 3x - 2
\]
\[
g(x) = 2x + 1
\]

Now, compute \(f(x) - g(x)\):

\[
f(x) - g(x) = (3x - 2) - (2x + 1)
\]

Distributing the negative sign:

\[
= 3x - 2 - 2x - 1
\]

Now combine like terms:

\[
= (3x - 2x) + (-2 - 1)
\]
\[
= x - 3
\]

Thus, \((f - g)(x) = x - 3\).

The answer is \(\text{D. } x - 3\).

Yes, that's correct! The result of \( (f - g)(x) \) is \( x - 3 \). So the answer is indeed \( \text{D. } x - 3 \).
