(a) Define the terms "range" and "co-domain" of a real-valued function.
(b) Give one example of a function in which the co-domain is larger than the range and clearly identify both sets.
(c) For the function f:R→R defined by f(x)=x3, explain in detail why the range of f is the set of all real numbers.
