i was randomly searching things about functions and i was teaching myself domain and range. i understand those.
however, i don't understand even and odd functions
i understand the basic ones like x^2 |x| and cos x are even and x^3 sinx and tanx are odd..
i was wondering what these were:
f(x)= log base 2 x
f(x)= square root of x
and f(x)= square root of a^2 - x^2
