f(x) = ∛(x - 4)

f(-121) is x = -121

f(31) is x = 31

<u>Step 2: Evaluate</u>

f(-121)

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

f(31)

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