Hi there,
I've been having a little bit of trouble with this derivative homework of mine.
It says that f(x) = (-4x -3) / (x^2 -x +4)
I need to find the zeros/roots of this function, and I only got a zero when x= - 3/4...are there any others?
Also, we need to find the intervals on which the function is increasing/decreasing.
I found the first derivative to be (4x^2 +6x -19) / (x^2 -x +4)^2
But I cannot find any x-value where f ' (x) is 0 or undefined...
Therefore I can't find when the function is increasing or decreasing.
I had no trouble with the second derivative and inflection points, but another question asks if the original function has any vertical asymptotes. I cannot find any, but did anyone else?
