Your question is -
If f(x) = x + 9 / 3, then find the value of f(2) , then which one is correct?

Your Correct answer: e

See the details Explanation:
According to the question,
f(x) = (x + 9)/3……. (i)
We have to find the value of f(2).
Thus, substituting, x=2 in equation (i), we get,
f(2) = (2 + 9)/3
∴ f(2) = 11/3 = 3.6667
But, none of the given options represent this value.

Hence, the correct answer is option e.
