A graph showing some of the formulas related to the 2^2x+1 problem, created by Aaron Sherman in 2007 using gnuplot:
set terminal svg set output "2xplus1.svg" set grid; set xlabel "X"; set ylabel "Y"; set logscale y 2; set label "(4,23)" at 4,23 point lt 1 pt 2 ps 3 offset 1,-1; set label "(0,2)" at 0,2 point lt 1 pt 2 ps 3 offset 1,-1; plot [x=-5:20] [:] sqrt(1+2**x+2**(2*x+1)), 2**((2*x+1)/2)+1;
