Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle f(x) = 3^x$

Step 2: Evaluate

1. Substitute in x [Function f(x)]:                                                                           $\displaystyle f(-2) = 3^{-2}$
2. Rewrite [Exponential Property - Rewrite]:                                                      $\displaystyle f(-2) = \frac{1}{3^2}$
3. Exponents:                                                                                                       $\displaystyle f(-2) = \frac{1}{9}$
