Question 696573
It's not even, because replacing (x) with (-x) does 
not give the same value of f(x), which is a reflection
about the vertical axis.
---------------------
It is an odd function because replacing (x) with (-x) 
changes the sin of f(x)
{{{ f(x) = x^5 }}}
{{{ f(-x) = (-x)^5 }}}
-----------------
and, likewise
{{{ f(-x) = (-x)^5 }}}
{{{ f(x) = x^5 }}}
