I 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.
no 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
