Here are some graphs of common functions.
As you might notice, I made these graphs using the `gnuplot` program.

## y = x^{ 2}

## y = x^{ 3}

## y = sqrt(x)

## y = e^{ x}

## y = log x

## y = sin x

## y = cos x

## y = tan x

I also have a small collection of interesting
absolute value functions that you might want to
