Question
Consider two one-to-one functions
f and
g for which the following statements are true:
• Domain of f is (0, 3).
• Domain of g is [-1, 00).
• Image of f is (-∞, ∞).
• Image of g is (-2, 2].
• f(2) = 0
• g(0) = 1
(a) Why should we believe that f(1) # 0? because f is one to one and f(2) is already 0. .
(b) Write the domain of f -1:
(c) Write the image of f -1:
(d) Find the value of (f-l•g-1)(1) =
