D.
g(x) = 9x - 6

Answer: Option C

[tex]g(x) = 4 ^ x-1[/tex]

Step-by-step explanation:

If we have a function f(x) and we want to move its graph vertically then we apply the transformation:

[tex]g (x) = f (x) + k.[/tex]

So:

If [tex]k> 0[/tex] the function g(x) will be the function f(x) displaced k units up

If [tex]k <0[/tex] the function g(x) will be the function f(x) displaced k units down.

In this case we know that the graph of f(x) moves 5 units up.

then [tex]k> 0[/tex] and [tex]k = 5[/tex]

Therefore [tex]g (x) = f(x) +5[/tex]

[tex]g(x) = 4 ^ x - 6 +5\\\\g(x) = 4 ^ x-1[/tex]
