Mark the correct alternative in each of the following:
Let f(x) = x3 be a function with domain {0, 1, 2, 3}. Then domain of f–1 is
Given that f(x) = x3 be a function with domain {0, 1, 2, 3}.
Then range = {0, 1, 8, 27}
f can be written as {(0, 0), (1, 1), (2, 8), (3, 27)}
f-1 can be written as {(0, 0), (1, 1), (8, 2), (27, 3)}
So, the domain of f–1 is {0, 1, 8, 27}
