Answer:
You can't solve this with only this much info.
Step-by-step explanation:
There are 2 varibles y and x. You have to at least have 2 different equations with only variables y and x or know the value of one. Of course you could guess but then there would be multiple answers. like y=1, x=2.5, etc.
f(5) = 17
plug in 5 in the x so 3(5)+2 =17
The answer I got was 7 7/10
(sorry if wrong!)
Therefore,
25. Its cubed.
