To find \((f+g)(x)\), we need to add the functions \(f(x)\) and \(g(x)\).

Given:

  • \(f(x) = 3x - 4\)
  • \(g(x) = 3x + 6\)

Now, we can calculate \((f+g)(x)\):

\[ (f+g)(x) = f(x) + g(x) = (3x - 4) + (3x + 6) \]

Now, combine like terms:

\[ = 3x + 3x - 4 + 6 \] \[ = 6x + 2 \]

Thus, \((f+g)(x) = 6x + 2\).

Now we can fill in the missing values:

\((f+g)(x) = _ \cdot x + _ \)

The answers are:

\((f+g)(x) = 6 \cdot x + 2\)

So the missing values are \(6\) and \(2\).
