Please show us exactly what the answer key says. Perhaps you are misinterpreting it.View attachment 34724
This doesn't make sense, this piecewise function isnt continuous at x = 1. If it's not continuous why is the answer key telling me it is differentiable.
If a function isnt continuous it isn't differentiable.
Thanks. The one odd thing about this answer is that it claims the function is differentiable at x=1. Just change that from "x≤1"to "x<1" and it would be correct. Looks like a typo!
Of course not. But it can be differentiable everywhere else.Wait, If a function isnt continuous in a certain point is the function as a whole still differentiable. I am confused
