Tutorial Exercise Verify that fhas an inverse function. Then use the function f and the given real number a to find (R-1)(a). (Hint: See Example 1. If an answer does not exist, enter DNE.) f(x) = x3 - 4, a = 121 Step 1 The given function is f(x) = x - 4. Differentiate f(x) with respect to x. f'(x) = 3 3 x Step 2 The function f'(x) = 3x2 is always non-negative non-negative on the domain of f(x)....
