Explanation:

Step 1: Define

f(x) = ∛(x - 4)

f(-121) is x = -121

f(31) is x = 31

Step 2: Evaluate

f(-121)

  1. Substitute in x: f(-121) = ∛(-121 - 4)
  2. [Radical] Subtract: f(-121) = ∛(-125)
  3. [Radical] Evaluate: f(-121) = -5

f(31)

  1. Substitute in x: f(31) = ∛(31 - 4)
  2. [Radical] Subtract: f(31) = ∛27
  3. [Radical] Evaluate: f(31) = 3
