If a function is differentiable at a point, it is also:
AConstant there
BIncreasing there
CUndefined there
DContinuous there
Answer & Solution
Correct answer: D. Continuous there
1. Differentiability is the stronger condition.
2. It cannot hold where the graph breaks.
3. So a differentiable function is continuous at that point.
4. The answer is continuous there.
