Homework Statement
a. Compute the limit for f(x) as b goes to 0
Homework Equations
$$f(x) = \frac{(a+bx)^{1-1/b}}{b-1}$$
##a \in R##, ##b\in R##, ##x\in R##
The Attempt at a Solution
##a+bx## goes to ##a##
##1/b## goes to ##\infty## so ##1-1/b## goes to ##-\infty##
##(a+bx)^{1-1/b}## then goes to 0
##b-1## goes to -1
I have no ideas how to combine and conclude. Which mathematical property/rule can I use?
