Title: clean up section 1.4 text/figure correlation for Gamma function

First off, I'm not sure this is correct as I don't yet understand the Gamma function. Hence the 'maybe' in the branch name. However, it seems clearer to use g(x) rather than f(x) in the figure and I think that the variable should be 'x' instead of 'z'.
