1) function will not be differentiable at point where its not continuous.
2) function is not differentiable for points
3) curve has horizontal tangent at point y' = 0
i.e.
I just need to know how what I have to do in each situation1. I'm given a piece-wise function graph and i'm to determine the value(s) of x where the function is not differentiable. How would i do this?
2. y . Determine the value(s) of x where the function is not differentiable.
3. At what points does the curve y have horizontal tangents?
