<u>Step 1: Define</u>

<em>Identify</em>

\displaystyle f(x) = 3^x

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [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}
