Answer 2

Answer: The required value of f(3) is 81.

Step-by-step explanation: We are given the following function :

`f(x)=\left((1)/(9)\right)9^x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

We are to find the value of f(3).

Substituting x = 3 in equation (i), we get

`f(3)\\\\\\=\left((1)/(9)\right)*9^3\\\\=9^2\\\\=81.`

Thus, the required value of f(3) is 81.
