Question

Supposed f(x) = 6x - 2 and g(x) = 2x + 4.
What is (f - g) (x)?
Hint - Subtract f(x) and g(x) &, distribute the negative to g(x) and combine like terms.

Answer 1

To find \((f - g)(x)\), we start by subtracting \(g(x)\) from \(f(x)\).

Given:
- \(f(x) = 6x - 2\)
- \(g(x) = 2x + 4\)

Now, we can express \((f - g)(x)\) as follows:

\[
(f - g)(x) = f(x) - g(x) = (6x - 2) - (2x + 4)
\]

Distributing the negative sign:

\[
(f - g)(x) = 6x - 2 - 2x - 4
\]

Now, combine the like terms:

\[
(f - g)(x) = (6x - 2x) + (-2 - 4) = 4x - 6
\]

Thus, the final answer is:

\[
(f - g)(x) = 4x - 6
\]
