f(x)=\frac{1}{9}(3^x)

If the function is asking what if x = 5, then we will substitute the exponent x with 5.

f(5)=\frac{1}{9}(3^5)

From the formula above, we will multiply 3 to itself five times (3 x 3 x 3 x 3 x 3) = 243

f(5)=\frac{1}{9}(243)

After that, we will multiple 243 to 1/9 or simply divide 243 by 9.

f(5)=\frac{243}{9}=27

Therefore, the value of the function if x = 5 is 27. Option A is the answer.
