Answer:
hiii...hopefully this is correct x=12
To find your constant of variation, you just need to figure out what you multiply the x by in order to get f(x). In other words, what do you multiply the 3 by to get 6? What do you multiply the 7 by to get 14? Another way to think of it is to divide f(x) by the x to get your constant.
The answer is D-16
16/4= 4. 4x3=12. 12-2=10
