I think I know the answer, but the internet is confusing me. (Yes I realize the Flood will most likely be more confusing.)

Also, an explanation would be totally A+

Shouldn't this be posted in that topic about procrastinating about homework?

I am assuming direct control.

I don't think so, f(x) has to be continuous for it to be differentiable.

Why are you looking at this?

Correct. In order for f(x) to be differentiable, it must be continuous at all points within its domain.

Depends what you mean exactly OP. You can differentiate a function that has discontinuities in it, but the derivative will also be discontinuous at those point.

This.

1/x is differentiable, but not continuous. The discontinuity occurs at x=0, which is likewise the point of discontinuity of its derivative, -1/x^2.
