12/18 = 8/x <=> 2/3 = 8/x <=> x = (3*8)/2 = 12;

Answer:

$g(x)=x+8$

Step-by-step explanation:

Translating a function up is very simple, all you need to do here is add 8.

If you want to think of it logically,

$f(x)=x$

the whole right side of the function here can be our output. If x is 8, then the output, or height, is also 8. if you wanted to translate that up to 10, you'd simply need to add 2 to it, meaning $x+2$ . Then, at any given point on the function, it'd be 2 higher than it would be otherwise.
