The transformations you have seen in the past can also be used to move and resize graphs of functions. We will be examining the following changes to f (x): - f (x), f (-x), f (x) + k, f (x + k), kf (x), f (kx) reflections translations dilations. Reflections of Functions: -f (x) and f (-x)
The Fourier Transform is enough of a description for decently well defined functions (or signals) that are not having infinite energy (and, by use of the dirac delta function, can be extended to certain finite power, infinite energy functions, like DC or a sinusoid or a periodic function.)
