$f (x + 2) = 3^{x + 2}$ $f(x+2)=3^(x+2)$

In these kind of questions, we replace the "x" term with what is within the brackets. So in this question, we have:

$f (x) = 3^{x}$ $f(x)=3^x$

and we're looking for $f (x + 2)$ $f(x+2)$ , so we replace the $x$ $x$ with $x + 2$ $x+2$ , so we have:

$f (x + 2) = 3^{x + 2}$ $f(x+2)=3^(x+2)$

Let f(x)=3xf(x)=3^x, what is the value of f(x+2)?
