Find the inverse of the following function. Find the domain, range, and asymptotes of each function.
Graph both functions on the same coordinate plane
x/3
f(x)=4+e
( if this makes sense, not sure how else to show it. the x/3 is after the e like x/3 to the power of e)
please help me! show steps also, if i an just given an answer that wont help me! thanks in advance!!!

y = 4+e^x/3
y4 = e^x/3
ln(y4) = x/3
x = 3ln(y4)
so, f inverse = 3ln(x4)
for domain, recall that ln(u) is defined only for u>0
domain for exponentials and range for logs is all reals
