Consider the first five terms of the following sequence.
3, 12, 48, 192, 768, ...
If the sequence defines a function, what is a reasonable domain and range of the
function?
a) Domain: (1, 2, 3, 4, 5, ...); Range: 3, 12, 48, 192, 768, ...}
b) Domain: {1, 2, 3, 4, 5, ...);
Range: all real numbers
c) Domain: all real numbers; Range: {3, 12, 48, 192, 768, ...)
d) Domain: all real numbers; Range: all real numbers
