I think the answer is f(2)=6 , but I'm not too sure. Hope this helped somehow!
Answer in fraction form = 9/8
Answer in decimal form = 1.125
note: the improper fraction 9/8 converts to the mixed number 1 & 1/8
To get this answer, we divide both sides by 8 to isolate n. The expression 8n really means "8 times n". We divide to undo the multiplication.
Multiply 2/3 by 8 and you will get 16/3 or 5.33 repeating.
