Red line[edit]
Should the red line in this plot be -e^-x rather than e^-x? KennethJ (talk) 09:30, 3 September 2011 (UTC)
- No. The function will have negative values for all real values for x and will be below the X-axis whereas the function will be positive for the same values of x and will be above X-axis.--ElectroKid (talk • contribs) 19:08, 3 September 2011 (UTC)
- The current description defines as a linear combination involving rather than one involving , so that may be what Kenneth meant. I'd also say that averages are easier to visualize than "half the difference". Symplectic.Nova (talk) 14:52, 3 July 2012 (UTC)
