Step-by-step explanation:

Step 1: Define

Identify

f(x) = 3ˣ

f(-2) is x = -2 for function f(x)

Step 2: Evaluate

  1. Substitute in x [Function f(x)]:                                                                           f(-2) = 3⁻²
  2. Exponents:                                                                                                        f(-2) = 1/9
