Step-by-step explanation:

Step 1: Define

f(x) = 1/4(2)ˣ

f(5) is x = 5 for function f(x)

Step 2: Evaluate

  1. Substitute in x [Function]:                                                                                f(5) = 1/4(2)⁵
  2. Exponents:                                                                                                        f(5) = 1/4(32)
  3. Multiply:                                                                                                             f(5) = 8
