Hi all, hope someone could help me. I'm trying to find domain, range and asymptotes for the following functions.

f(x) = 5 - e^(x-1)
g(x) = ln(5 - y) + 1

    The variable on the right side of g(x) should be x, not y.

    Take a close look at the functions. Plotting some points may help.

    Review the definitions of domain, range and asymptote and tell us what you think.

    As for the domain: Are any values of x not allowed?

    Hint: You cannot take the log of a negative number or zero.

    Sorry, typo...
