alleryThe derivative of a function at a point is defined using a:
AA total
BA power
CA limit
DA count
Answer & Solution
Correct answer: C. A limit
1. The definition compares values at a point and just beyond it.
2. That comparison is taken as the gap shrinks to nothing.
3. So the derivative is defined by a limit.
