Here's the problem that my friends and I are struggling with. We have 55 summer questions to do and we're stumped on these. Could anyone help?
(I don't know how to write exponents within this text, so I used words - I hope it is clear.)
There are two expressions. Answer a)., b)., and c). for each expression.
Expression #1) f(x) = (x-3)/(x+5)
Expression #2) f(x) = 3(2 to the x power)
Question a). Find (f to the negative 1st power)(x)
Question b). Compute (f of f to the negative 1st power)(x)
Question c). Compute (f to the negative 1st power of f)(x)
Thanks to anyone who can help.
