Secondary question from student.
I need to know:
There is one function with the domain of all real numbers that is both even and odd. Please give me the answer to this question before I go insane.
A function f is even if for every x in its domain f(x) = f(-x)
Thus a function f is both even and odd if for every x in its domain
So, whatever f(-x) is, it has the property that
the only number a that satisfies a = -a is zero and thus f(x) = 0 for all x.
