# Fourier transform time and frequency question?
So there is an example in my book where g(k) is converted to G(f) and its written
$$g(k)\Longleftrightarrow G(f)$$
So:
$$a^ku(k)\Longleftrightarrow \frac{1}{1-ae^{-j2\pi f}}$$
My question is, how do we find that $a^ku(k)\Longleftrightarrow 1/(1-ae^{-j2 \pi f})$ ?

even/odd graph
Are the graphs of
$\sqrt{x}$
$2^x$
$log_2x$
even or odd? I don't see any symmetry with respect to y axis or origin. Thanks!
