To find $g(x) - f(x)$, you subtract the function $f(x)$ from $g(x)$.

Given: $g(x) = 6x + 4$ $f(x) = 2x - 7$

Now, subtract $f(x)$ from $g(x)$:

$g(x) - f(x) = (6x + 4) - (2x - 7)$

Distribute the negative sign across $f(x)$:

$g(x) - f(x) = 6x + 4 - 2x + 7$

Now, combine like terms:

$g(x) - f(x) = (6x - 2x) + (4 + 7)$

$g(x) - f(x) = 4x + 11$

So, the correct answer is:

D. $4x + 11$
