**bobpursley**, Tuesday, August 28, 2012 at 5:59pmI am not exactly certain of your function, I think it is this:

y=(4+e^-x)/3

e^-x=3y-4

take ln of each side

-x= ln(3y-4)

then swap variables

y=-ln(3x-4) which is the inverse function.

**Bree**, Tuesday, August 28, 2012 at 6:03pmno thats not it, i am not sure how to show it on here but the -x/3 is on the side of the e. like if you had 2^3 it would be, (2)(2)(2). that is what the e^-x/3 should represent. if this makes sense
