The g -1({0}) for the function g(x)= ⌊x⌋ is ________.
A. {x | 0 ≤ x < 1}
B. {x | 0 < x ≤ 1}
C. {x | 0 < x < 1}
D. {x | 0 ≤ x ≤ 1}
Answer:D
The g -1({0}) for the function g(x)= ⌊x⌋ is ________.
A. {x | 0 ≤ x < 1} B. {x | 0 < x ≤ 1} C. {x | 0 < x < 1} D. {x | 0 ≤ x ≤ 1}
Explanation: g({0}) for the function g(x) is {x | 0 ≤ x ≤ 1}. Put g(x) = y and find the value of x in terms of y such that ⌊x⌋ = y. [/expand]
