multistep problem involving f''(x) and horizontal tanget lines
Exactly as is
1. Given the function f(x) = find the points on the domain of f at which f'(x) is zero. Also find the points on the domain at which f''(x) is zero, when possible give exact answers.
2. repeat for f(x) = where . again when possible exact answers should be given.
3. Find the equation of the tanget line to the graph
In regards to number 1, I should derive it and find where y = 0; and then to find f''(x) I would find the derivative squared?
Assuming that logic is correct, I would repeat for number two with the new info.
3, I am not focusing on yet but, it should just be finding the derivative and then creating an equation...
