Assuming your question is f(x) = -x / 3 +2 and required to find f(1) / f(3)

Explanation:

The answer is 5/3

We have,

f(x) = -x / 3 +2

Now to find f(1) / f(3) , we find values of f(1) and f(3)

For finding the value of f(1)

Take,
f(x) = -x / 3 +2 (according to the question)

Now, replace the 'x' with 1 for f(1)

Then,
f(1) = -1 / 3 +2
or, f(1) = 5 / 3 (from calculations)

Similarly for f(3)

Now, replace the 'x' with 3 for f(3)
Then,
f(3) = -3 / 3 +2
or, f(3) = 1 (from calculations)

Hence,

We have the values for f(1) and f(3) as 5/3 and 1 respectively

Now,

f(1)/f(3) = "5/3"/ 1 (keeping the values of f(1) and f(3)

We get,

f(1)/f(3) = 5/3

Which is your answer.
