Question

Let X = \{1, 2, 3, 4, 5\} and Y = \{a, b, c, d, e\}, and define $h: X \to Y$ as follows: $h(1) = b$, $h(2) = a$, $h(3) = b$, $h(4) = b$, $h(5) = d$ Let A = \{1, 2\}, C = \{a, b\}, and D = \{c\}. Then (1) h(A) = C [Select] [Select] False (2) $h^{-1}(C) =$ True (3) $h^{-1}(D) \neq \emptyset$ [Select] (4) h(X) = Y [Select]

          Let X = \{1, 2, 3, 4, 5\} and Y = \{a, b, c, d, e\}, and define $h: X \to Y$ as follows:
$h(1) = b$, $h(2) = a$, $h(3) = b$, $h(4) = b$, $h(5) = d$
Let A = \{1, 2\}, C = \{a, b\}, and D = \{c\}. Then
(1) h(A) = C [Select]

False
(2) $h^{-1}(C) =$
True
(3) $h^{-1}(D) \neq \emptyset$ [Select]
(4) h(X) = Y [Select]

$Let X = {1, 2, 3, 4, 5} and Y = {a, b, c, d, e}, and define h: X → Y as follows: h(1) = b, h(2) = a, h(3) = b, h(4) = b, h(5) = d Let A = {1, 2}, C = {a, b}, and D = {c}. Then (1) h(A) = C [Select] [Select] False (2) h^-1(C) = True (3) h^-1(D) ≠∅ [Select] (4) h(X) = Y [Select]$
