See a solution process below:

For each of these values of $x$ $x$ we need to substitute the value of $x$ $x$ for $x$ $x$ in the function and calculate the result:

$f (- 2) = 3^{- 2}$ $f(color(red)(-2)) = 3^color(red)(-2)$

$f (- 2) = \frac{1}{3^{2}}$ $f(color(red)(-2)) = 1/3^color(red)(2)$

$f (- 2) = \frac{1}{9}$ $f(color(red)(-2)) = 1/9$

$f (- 1) = 3^{- 1}$ $f(color(red)(-1)) = 3^color(red)(-1)$

$f (- 1) = \frac{1}{3^{1}}$ $f(color(red)(-1)) = 1/3^color(red)(1)$

$f (- 1) = \frac{1}{3}$ $f(color(red)(-1)) = 1/3$

$f (0) = 3^{0}$ $f(color(red)(0)) = 3^color(red)(0)$

$f (0) = 1$ $f(color(red)(0)) = 1$

$f (1) = 3^{1}$ $f(color(red)(1)) = 3^color(red)(1)$

$f (1) = 3$ $f(color(red)(1)) = 3$

Now that you know the pattern, see if you can do:
