Also x? :\

1) e^(ln(x)) == ln(e ^ x) == x
2) ln(e^x) == x

dom f o g = ran g

dom g o f = dom g = ran f

 if f = ln
  • and g
  • = e^x


:. f[g
  • ] = ln[e^
  • ]

              = x, x belongs to R

:. g[f
  • ] = e^[ln
  • ]

              = x, R+

Well I'm not 100% sure but possibly mid 30s could be wrong though.

er, you are right if you're talking about exam 1 (gg me, l2context), the exam 2 marks were still very poor.

The mean was 54%, but A+ cutoff was indeed 93.75% (http://www.vcaa.vic.edu.au/vce/statistics/2006/gradeassess/vce_math_methods_ga06.pdf)

Which brings me to: why, why oh why is 54.5% considered a B -.-.
