y= 9e^(x)/ 2e^(x)+ 1

Please Show Work

**Steve**, Monday, November 7, 2011 at 1:02pmI assume that's 9e^x/(2e^x + 1)

Otherwise, y = 9/2 + 1 = 11/2, which is not very interesting.

y' = [9e^x (2e^x + 1) - 9e^x * 2e^x]/(2e^x + 1)^2

y' = [18e^(2x) + 9e^x - 18e^(2x)]/(2e^x + 1)^2

y' = 9e^x/(2e^x + 1)^2

Hmm. How about that?
