7.give an example of a sequence x s.t. the range of x has exactly 3 elements.
8.is the following a function from the indicated domain to the indicated codomain?If it is not a function show that the function is not well defined by naming an equivalence class in the domain that is assigned two different values.
f: Z_3-->Z_6 given by f(x bar)={2x}
where we represent an element of the domain as an equivalence class x bar, and use the notation [x] for equivalence classes in the codomain.
14.For the canonical map f:Z-->Z_6, find
a)f(3)
b)the image of 6
c)a pre-image of 3 bar
d)all pre-images of 1 bar
