what up everyone
im stuck on this question and has hoping i could get some help,
so i am given the log function of f(x)=-5log(7x+11)+11
(the log is of base 10 btw if that makes a difference) the first part of the question says that the largest domain of f if x>a what is the value of a? and the second question says suppose b is a number for which both b and 1000b + 10989/7 are in the domain of f(x). find the simplest possible expression for f(1000b + 10989/7 - f(b)?
cheers
