We just did derivatives, so I know how to do that. I've found a lot of information on how to find the intervals of where a function is increasing or decreasing, but not with an x value already given.
Determine if the function is increasing or decreasing at x=2.
1. f(x) = x^3 - 7x + 1
2. f(x) = (x - 3)^4
3. f(x) = cubed root of (x - 1)
4. f(x) = (x + 1)/(x - 2)
Thanks in advance!!!
