Answer:

a = 9, b = 3, c = 1

Explanation:

Using the rules of exponents


a^(-m)
(1)/(a^(m) )
a^(m) =
(1)/(a^(-m) ) and
a^(0) = 1

Given

f(x) =
((1)/(3)) ^(x), then

f(- 2) =
((1)/(3)) ^(-2) =
(1)/(3^(-2) ) = 3² = 9 ⇒ a = 9

f(- 1) =
((1)/(3)) ^(-1) =
(1)/(3^(-1) ) =
3^(1) = 3 ⇒ b = 3

f(0) =
((1)/(3)) ^(0) = 1
