Given:

The function is


f(x)=\left((1)/(3)\right)^x

To find:

The missing values for a, b, and c in the given table.

Solution:

We have,


f(x)=\left((1)/(3)\right)^x

At x=-2,


f(-2)=\left((1)/(3)\right)^(-2)


a=\left(3\right)^(2)
\left[\because \left((a)/(b)\right)^(-n)=\left((b)/(a)\right)^(n)\right]


a=9

At x=-1,


f(-1)=\left((1)/(3)\right)^(-1)


b=\left(3\right)^(1)
\left[\because \left((a)/(b)\right)^(-n)=\left((b)/(a)\right)^(n)\right]


b=3

At x=0,


f(0)=\left((1)/(3)\right)^(0)


c=1
\left[\because a^0=1, a\\eq 0\right]

Therefore, the missing values of a,b and c are 9, 3, and 1 respectively.
