Hello, I have a homework assignment where I need to write my solution in such a way that someone else can follow along. Trouble is, I can't even figure out how to get the problem started (so, I probably can't get it finished either.)
The question/problem is:
Find the derivative or f(x)= 1/sqrt (x^2 + 3x -4) by the definition. In other words, use lim h-> 0 (f(x+h) -f(x))/h
Should I start by taking the denominator, moving it up with a -1/2 power and ??
The examples in class were not near as difficult. :/
Thanks for any help.
