Right skewed arc. Just graph it with a calculator if you wan to see it.
I am having trouble with this problem
Use a graphing utility to graph the function on the closed interval [a, b].
f (x) =(x/2)-sin(pi*x/6) [−1, 0]
Determine whether Rolle's Theorem can be applied to f on the interval.
If Rolle's Theorem can be applied, find all values of c in the open interval (a, b) such that f '(c) = 0. (Enter your answers as a comma-separated list. Round your answers to four decimal places. If not possible, enter IMPOSSIBLE.)
What trouble are you having? Drawing the graph with a graphing utility? Do you know what Rolles Theorem says? Are you having trouble:
Determining if Rolles Theorem can be applied? (Can you evaluate f(-1)? Can you evaluate f(0)? Can you see whether or not f is continuous over the given interval?) Can you differentiate f? Can you solve the resulting equation f'(x) = 0?
It is no good saying "I'm having trouble". You need to show what you've been able to do and then say where you're having trouble.
