Answer:
The value of f(0)=1
Step-by-step explanation:
We are given that


(6,1) and (8,1) lies on the graph of y=f(x)
We have to find the value of f(0).



By comparing ,we get
k=1
Therefore, 
Now, substitute x=0

Hence, the value of f(0)=1
6, Bob will have 6 apples after he gives 14 away.
To solve this problem, we must first understand what it is asking. Since Bob is giving away apples, he is subtracting them from his total amount. So, now we do the subtraction.
20 - 14 = 6, so Bob will have 6 apples after he gives 14 away.
The answer is C. f(n)=f(n-1)•3
Look at the photo I attached it shows how.
Hopefully this helps. This is how I was taught.
